* toolchain-external-custom: allow specifying relative path to binariesGravatar Calin Crisan2018-04-192-1/+14
| | | | | | | | | | | | | | | | | | There are cases where a downloaded toolchain doesn't have its binaries placed directly in a "bin" subfolder (where BuildRoot currently looks for them). A common example is the official Raspberry Pi Toolchain (https://github.com/raspberrypi/tools), which has its binaries in "arm-bcm2708/arm-linux-gnueabihf/bin".

* toolchain-wrapper: use -ffp-contract=off on MIPS Xburst for gcc >= 4.6Gravatar Waldemar Brodkorb2018-04-012-0/+9

* pkg-cmake: install CMake files as part of a packageGravatar Thomas Petazzoni2018-03-251-3/+0
| | | | | | | | | | | | | | | | | | | | Currently, the toolchainfile.cmake and Buildroot.cmake files are installed outside of any package, just triggered by the toolchain target. As part of the per-package SDK effort, we are trying to avoid anything that installs to the global $(HOST_DIR), and this is one of the remaining files installed in $(HOST_DIR) outside of any package. We fix this by installing such files as part of the toolchain package post-install staging hooks. Yes, a post-install staging hook to install things to $(HOST_DIR) is a bit weird, but the toolchain infrastructure is made of target packages only, and they all install a lot of stuff to $(HOST_DIR) already.

* toolchain: limit musl/kernel headers conflict workaroundGravatar Baruch Siach2018-02-141-6/+6
| | | | | | | | | | | | | | | | | | | | | The musl/kernel headers workaround was added in commit 196932cd91 (toolchain: workaround musl/kernel headers conflict) to fix definition collisions in networking related headers between musl headers and kernel headers. Kernel headers from version 4.15 and newer do not need this workaround anymore since kernel commit c0bace798436bc (uapi libc compat: add fallback for unsupported libcs). The C library does not have to define the __GLIBC__ macro to make the __UAPI_DEF_* macros effective. Updated the comment to accordingly. Tested with the xl2tp package. This package fails to build with older kernel headers without the workaround (struct in_pktinfo redefinition, among others). With 4.15 headers, xl2tp builds fine with this patch applied. That is, no workaround needed. Cc: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Signed-off-by: Baruch Siach <baruch@tkos.co.il> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com>

* toolchain: post-pone evaluation of TOOLCHAIN_EXTERNAL_BINGravatar Thomas Petazzoni2017-12-311-1/+1
| | | | | | | | | | | | | | | | | | The upcoming per-package SDK functionality is heavily based on the fact that HOST_DIR, STAGING_DIR and TARGET_DIR are evaluated during the configure/build/install steps of the packages. Therefore, any evaluation-during-assignment using := is going to cause problems, and need to be turned into evaluation-during-use using =. This patch fix up one such instance in the external toolchain code. This change is independent from the per-package SDK functionality, and could be applied separately.

Resolution is simple: add him for both. - linux/Config.in, because we updated the 4.13.x release used by default in master, while we moved to 4.14 in next. Resolution: use 4.14. - package/libupnp/libupnp.hash: a hash for the license file was added in master, while the package was bumped into next. Resolution: keep the hash for the license file, and keep the hash for the newest version of libupnp. - package/linux-headers/Config.in.host: default version of the kernel headers for 4.13 was bumped to the latest 4.13.x in master, but was changed to 4.14 in next.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the possibility to choose the floating point mode (32, xx or 64) is conditional on having a sufficiently recent gcc version. Which means that the architecture selection depends on the gcc version. But that's opposite to what we've always done in Buildroot: the software versions are conditional to the architecture options. There is nothing we can do about the hardware: it is there, we can't change it, while we can restrict ourselves to using software that is working on said hardware. Thus, we inverse the logic, to move the condition onto the software side: whenever mfpxx is selected, we restrict the toolchain selection to at least a gcc-5. And now, the blind BR2_TOOLCHAIN_HAS_MFPXX_OPTION symbol is no longer needed, so we get rid of it. Signed-off-by: "Yann E.

| * arch/arm: some variants need different gcc versionsGravatar Yann E. MORIN2017-11-241-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Take the conditions currently specified in the gcc version choice. Also, the conditions explained in the commit log for 78c2a9f7 were not all properly applied, especially the a57-a53 combo needs gcc-6, but 78c2a9f7 forgot to add the condition to gcc-4.9. gcc-4.9 was excluded for cortex-a17 and a72, but the CodeSourcery external toolchain, which uses 4.8, was not excluded for those two cores. Now it is. Remove the arch condition from gcc and the external toolchains. Signed-off-by: "Yann E.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When an architecture expresses a requirement on the gcc version, limit the version choice in the custom external toolchain. The rationale being that there is no point in offering that version to the user if we know before-hand that the gcc version will not work for that architecture. All versions below the minimum we support is just made conditional to that minimum as well, including the "older" entry. However, this means that the "older" entry is no longer available when the architecture requires a minimum gcc version. A user who wants to use a toolchain with a gcc older than the minimum will have no choice but to realise the toolchain is not suitable (or lie and we would catch that when checking the gcc version anyway).

* | Fix makefile include order by using sort/wildcard.Gravatar Peter Seiderer2017-11-241-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | The 'include' directive in GNU make supports wildcards, but their expansion has no defined sort order (GLOB_NOSORT is passed to glob()). Usually this doesn't matter. However, there is at least one case where it does make a difference: toolchain/*/*.mk includes both the definitions of the external toolchain packages and pkg-toolchain-external.mk, but pkg-toolchain-external.mk must be included first. For predictability, use ordered 'include $(sort $(wildcard ...))' instead of unordered direct 'include */*.mk' everywhere. Fixes [1] reported by Petr Vorel: make: *** No rule to make target 'toolchain-external-custom', needed by '.../build/toolchain-external/.stamp_configured'. Stop.

* toolchain/wrapper: fake __DATE_ and __TIME__ for older gccGravatar Yann E. MORIN2017-10-221-2/+73
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Starting with version 7, gcc automatically recognises and enforces the environment variable SOURCE_DATE_EPOCH, and fakes __DATE__ and __TIME__ accordingly, to produce reproducible builds (at least in regards to date and time). However, older gcc versions do not offer this feature. So, we use our toolchain wrapper to force-feed __DATE__ and __TIME__ as macros, which will take precedence over those that gcc may compute itself. We compute them according to the specs: https://reproducible-builds.org/specs/source-date-epoch/ https://gcc.gnu.org/onlinedocs/cpp/Standard-Predefined-Macros.html Since we define macros otherwise internal to gcc, we have to tell it not to warn about that. The -Wno-builtin-macro-redefined flag was introduced in gcc-4.4.0. Therefore, we make BR2_REPRODUCIBLE depend on GCC >= 4.4. gcc-7 will ignore SOURCE_DATE_EPOCH when __DATE__ and __TIME__ are user-defined. Anyway, this is of no consequence: whether __DATE__ and __TIME__ or SOURCE_DATE_EPOCH takes precedence, it would yield the exact same end result since we use the same logic to compute it. Note that we didn't copy the code for it from gcc so using the same logic doesn't imply that we're inheriting GPL-3.0. Signed-off-by: "Yann E.

* toolchain: add glibc support for ARCv2Gravatar Evgeniy Didin2017-10-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Finally there's working ARC port of glibc thanks to Vineet and Cuper! This port is based on pretty recent glibc's master branch and ARC changes are being reviewed now in glibc's mailing list. Thus we again have to use sources from our GitHub but as soon as there's a glibc release with our patches applied we'll switch to upstream releases and will drop our glibc GitHub repo alltogether. Note now we cut tags in glibc repo simultaneously with tags in Binutils and GCC repos and so to make sure everything works in the best way we plan to update glibc tag together with Binutils and GCC. Also note as of today ARCompact (AKA ARCv1 ISA) is not supported in glibc but we plan to fix it soonish so for now we make glibc intentionally dependent on archs38. Also note we are not creating directory "2.26" because all patches for glibc ver 2.26 applies to arc glibc port.
