2017-03-19Merge pull request #639 from stilor/tweak-gcc-movelibsAlexey Neyman7-101/+293
When moving gcc libs, prefer the same directory as libc
2017-03-17Add an option to "demultilib"Alexey Neyman1-20/+38
It turns out buildroot does not currently accept a toolchain where a dynamic linker does not reside in the multi-os-directory. Unfortunately this is how glibc installs itself on AArch64 without any extra tricks. So, provide an option to force everything into /lib or /usr/lib; patch to buildroot will be worked on separately.

2017-03-15Check libraries for compatibilityAlexey Neyman1-2/+54
... as we are going through various multilibs in ld.so.conf Signed-off-by: Alexey Neyman <stilor@att.net>
2017-03-13Create ld.so.confAlexey Neyman3-10/+40
Also a fix for CT_IterateMultilibs: it didn't pass multi_os_dir_gcc, so it only worked if the caller did *not* declare it as a local variable. Signed-off-by: Alexey Neyman <stilor@att.net>
2017-03-13Fix up ld.so symlinks for muslAlexey Neyman3-48/+91
Convert absolute targets to relative so that they are valid on the host, too. The procedure is very similar to uclibc, so it is moved into a common function. Signed-off-by: Alexey Neyman <stilor@att.net>
2017-03-12Move tools alias creation to a common functionAlexey Neyman4-19/+59
... and in addition to final toolchain aliasing, use it when configuring multilibs for glibc/musl. Note that uClibc does not need it, it is explicitly selecting the tools using CROSS_PREFIX. Signed-off-by: Alexey Neyman <stilor@att.net>
2017-03-10Disable Guile in make if building for host in canadianAlexey Neyman1-1/+7
make's configure uses pkg-config to detect if Guile should be enabled; on ArchLinux, this picks up Guile from build machine's pkgconfig and then it fails to compile. A better solution might be to create a ${CT_HOST}-pkg-config in buildtools/bin that would report "unsupported" for all packages. However a quick grep only showed pkg-config being used by GCJ (not sure if it will build in canadian cross - we don't have any samples with GCJ) and Blackfin simulator in GDB (Blackfin is not currently supported by crosstool-ng). Hence, leave such pkg-config implementation and testing for another day. Signed-off-by: Alexey Neyman <stilor@att.net>
2017-03-10When moving gcc libs, prefer the same directory as libcAlexey Neyman1-3/+12
If libc ended up in a directory other than /lib, place GCC's libs in that directory as well. Signed-off-by: Alexey Neyman <stilor@att.net>

2017-03-07Merge pull request #627 from dankm/freebsdAlexey Neyman5-17/+39
FreeBSD build support
2017-03-07Disable format warnings for clangAlexey Neyman1-0/+5
It picks up gettext string and results in [ERROR] messages from ct-ng when gettext strings happen inside an error() call. Signed-off-by: Alexey Neyman <stilor@att.net>
2017-03-07Skip building locales on macos, tooAlexey Neyman1-1/+1
--enable-hacker-mode is not sufficient, in 2.25 configure then fails while checking for sysdeps fragments that apply to a given configuration, and with that worked around, fails on binutils & compiler version check. In brief: if someone wants locales on cygwin/macos, you'd have to implement cross-localedef (similar to cross-rpcgen) in glibc and submit it upstream. Signed-off-by: Alexey Neyman <stilor@att.net>
2017-03-07Only add clang-specific flags to clangAlexey Neyman1-4/+32
I.e., only to CFLAGS_FOR_BUILD if the build is canadian. Signed-off-by: Alexey Neyman <stilor@att.net>
2017-03-07Use CHOST instead of CROSS_PREFIXAlexey Neyman1-1/+1
The latter does not prevent zlib's configure from overriding 'AR' with /usr/bin/libtool on macos, and that breaks canadian crosses. Signed-off-by: Alexey Neyman <stilor@att.net>
2017-03-06Explicitly use gcc for GMPDan McGregor1-0/+3
GMP's configure script tries to be too smart, and if it determines that it's not cross-compiling it chooses gcc or cc instead of the wrapper we create at the start of the build. Signed-off-by: Dan McGregor <dan.mcgregor@usask.ca>

2017-03-02glibc: hide native c++ executable from buildDan McGregor1-0/+4
If glibc's configure finds the host c++ executable it assumes that c++ should be enabled for the build. In case we don't have cross g++ built yet (ie, for headers), this causes the build to fail creating C++ headers. So hide C++ from the build. Signed-off-by: Dan McGregor <dan.mcgregor@usask.ca>
2017-03-02Use BUILD_PREFIX and BUILD_SUFFIX for gcc versionDan McGregor1-1/+1
It's possible that "gcc" is not the compiler being used for the build, so respect BUILD_PREFIX and BUILD_SUFFIX when finding its version. Signed-off-by: Dan McGregor <dan.mcgregor@usask.ca>
2017-03-02Use configure to find the processor countDan McGregor1-1/+1
configure.ac now finds how to count the CPUs in a system. Currently the getconf method and sysctl methods are supported. Adding more is easy enough. Signed-off-by: Dan McGregor <dan.mcgregor@usask.ca>

2017-02-28Require xz to be presentAlexey Neyman1-19/+3
Some software starts to adopt xz-only distribution (strace, gcc-linaro, ...). Better that than deal with cryptic errors like "cannot find strace-.tar.bz2". Signed-off-by: Alexey Neyman <stilor@att.net>
2017-02-27Require GNU sedAlexey Neyman5-50/+28
After much struggling with macos (BSD) sed and even getting everything work in crosstool-ng itself, I had to abandon that because some components rely on GNU syntax. Specifically, GNU libc uses '/.../{H;g}' (note absense of the separator after 'g'). So, revert the -r/-E detection and check for sed's being of GNU origin. MacOS people, sorry, but you'd have to install GNU sed. Signed-off-by: Alexey Neyman <stilor@att.net>

Fix the build of elf2flt on Cygwin
2017-02-23Fix the build of elf2flt on CygwinAlexey Neyman1-1/+0
The -lcygwin -lc actually breaks the build: elf2flt picks up the symbols for getopt/optarg via <getopt.h> in binutils-X.Y/include, where optarg is declared without dllimport attribute. Therefore it pulls in getopt() from libc/libcygwin, but since optarg is not prefixed with _imp__, it is pulled from libiberty. But the object file in libiberty also contains getopt() thus resulting in multiple definitions thereof. While there, kill extraneous -ldl passed into configure - configure detects -ldl successfully.

2017-02-14Determine whether -E/-r option selects extended regexpAlexey Neyman19-83/+91
... and then use the right option. See the note in scripts/functions on where we should use ${foo} and where just 'foo'; this boils down to whether we can expect the build tools override to be in effect (e.g. in the actual build scripts) or not (i.e. outside of scripts/build). While running in scripts/functions, or in scripts/crosstool-NG.sh the build tools override directory (.build/tools/bin) may have not been set up (yet, or at all). Also, modify the installed scripts (populate, xldd) accordingly. Signed-off-by: Alexey Neyman <stilor@att.net>
