2017-05-25Retire CT_CC_GCC_TARGET_FINALAlexey Neyman1-8/+4
Make this behavior default in case the core gcc backend is used for final compiler (i.e., for baremetal configurations). Not setting this option breaks canadian baremetal configurations, and not setting it makes little sense at all in any baremetal configuration (since in baremetal we don't have any libc to begin with).

2017-05-25Handle ming32 as a hostAlexey Neyman1-14/+35
zlib refuses to run configure with mingw32 host and insists that win32/Makefile.gcc is used instead. This requires a change in this Makefile to support static-only builds. Fixes #694. Signed-off-by: Alexey Neyman <stilor@att.net>

The generated sysnum.h is different for o32/n32/64 ABIs. This needs to be revisited; either do this for all architecutres or perhaps, compare the headers for various multilibs and combine them if the are identical. Signed-off-by: Alexey Neyman <stilor@att.net>

Instead, prepare the files as a part of bootstrap and install them. This avoids rebuilding these files in each working directory; they don't change anyway as they are generated from the same installed source. Signed-off-by: Alexey Neyman <stilor@att.net>

MinGW: add --enable-secure-api config option
2017-04-07libc/mingw: quote variable in comparisonTamir Duberstein1-1/+1
Building with CT_MINGW_TOOLS unset before this change produces: /usr/local/ct-ng/lib/crosstool-ng-1.23.0-rc2/scripts/build/libc/mingw.sh: line 212: [: =: unary operator expected
2017-04-07MinGW: add --enable-secure-api config optionTamir Duberstein1-0/+5
Without this flag, MinGW does not expose secure variants of functions such as strcpy_s. See https://sourceforge.net/p/mingw-w64/mingw-w64/ci/master/tree/mingw-w64-headers/crt/sec_api/string_s.h#l11.

Check for python2/python3 and if found, pass them to --with-python. Allow user to override the choice via a new config option. This fixes systems where there is no "python", only "python2" or "python3". Signed-off-by: Alexey Neyman <stilor@att.net>
2017-04-02Always build ncurses-for-buildAlexey Neyman1-25/+5
If the build machine lacks tic, we need to build it in the first pass even if host==build: ncurses Makefiles are not smart enough to build 'tic' first and use the just-built tic to compile fallback terminfo. Signed-off-by: Alexey Neyman <stilor@att.net>
2017-04-01Fix symlinking to multiarch tools on CygwinAlexey Neyman2-21/+11
On cygwin, creating both "foo.exe" and "foo" results in 'ln -sf' returning an error ("File exists"). However, ln silently removes the "foo.exe" in this case, so an attempt to re-run the same command manually then succeeds. Hence, make binutils.sh also create symlinks with .exe prefix, using the new & shiny routine. Signed-off-by: Alexey Neyman <stilor@att.net>
2017-03-31MinGW-W64 fixesAlexey Neyman2-52/+99
- libpthread requires iteration over multilibs, unlike the core, it does not detect and build multilibs by itself. - Disable parallel builds for mingw-w64 components; until mingw-w64 core builds clean, I am not trusting it. - Make the list of tools to build configurable - Turn on multilib in x86_64 sample. - Make warnings about tuple less redundant. As in, "one WARN is enough, no need to shout it three times". - Messages about various steps/substeps are more aligned with the rest of the components. - Use 'make' instead of ${make} to invoke the companion make just built, if applicable.

2017-03-27Fix up the sysroot issue for sh4 in a different wayAlexey Neyman4-53/+34
(see the comments in the code for details on the issue) Old workaround in 100-gcc.sh stopped working (probably, due to one of GCC version upgrades), so switch to the other approach originally described there: adjust the list of multilibs to not include the default target explicitly.

2017-03-22Make creation of ld.so.conf optionalAlexey Neyman1-2/+2
... enabled by default for multilib and disabled otherwise. Buildroot has been complaining about /etc/ld.so.conf presence for almost a year now and I missed that. After the release, xldd will be modified to query the compiler for the list of multilibs to search. This would be too invasive change before 1.23, though. Note that it may lead to configurations where xldd currently does not find the libraries (if both DEMULTILIB and CREATE_LDSO_CONF are turned off). This is not the default setting in Kconfig, though.

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.

2017-03-13Fix up ld.so symlinks for muslAlexey Neyman3-48/+91

... 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>

2017-03-07Skip 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>
