gnustep-base's configure is broken on FreeBSD 9.1 when used with libobjc2 r36872

[Marcus Müller]

Hi (David),

when configuring gnustep-base on FreeBSD 9.1 in conjunction with clang33 and libobjc2 r36872, it's currently broken (since July, 8th):

CC=/usr/local/bin/clang33 
CXX=/usr/local/bin/clang++33

$ ./configure --disable-mixedabi CC=${CC} CXX=${CXX}
[…]
checking whether objc really works... yes
checking if the compiler supports -fconstant-string-class... Segmentation fault (core dumped)
no
configure: error: Your compiler does not appear to implement the -fconstant-string-class option needed for support of strings.  Please check for a more recent version or consider using --enable-nxconstantstring

I'm doing nightly builds with clang33 on my FreeBSD 9.1 box (which hasn't changed in quite a while), thus I can narrow down the set of changes which has introduced this problem to libobjc2 r36850 or r36851 (both committed Mon, 08 Jul 2013).



I've configured gnustep-make and libobjc2 (in this order) like this:

gnustep-make
===========


$ ./configure --enable-objc-nonfragile-abi --enable-native-objc-exceptions --with-layout=fhs --enable-debug-by-default CC=${CC} CXX=${CXX}
$ gmake -j 8 && sudo -E gmake install

libobjc2
======

$ rm -rf Build; mkdir Build; cd Build
$ CC=${CC} CXX=${CXX} GNUSTEP_CONFIG=/usr/local/bin/gnustep-config GNUSTEP_INSTALL_TYPE=LOCAL LIBOBJC_NAME=objc2 CMAKE_C_COMPILER=${CC} CMAKE_CXX_COMPILER=${CXX} CMAKE_ASM_COMPILER=${CC} CMAKE_ASM_FLAGS=-c CMAKE_BUILD_TYPE=Release cmake ..
$ make -j 4 && sudo -E make install



Cheers,

  Marcus
