Re: Compiling gcc-3.4.6 on sparc Solaris 9

[Daniel Santos <daniel.dlds@gmail.com>]

Hello,

As to switching to gcc 4.9, can my currently installed gcc 3.4.6 build it ?
While sticking to the 3.4.6 version, I removed the solaris ld out of the way and am building it with gnu ld.

Right now I have the following error :

rm -f libv3test.a
ar cru libv3test.a testsuite_abi.o testsuite_allocator.o testsuite_hooks.o 
ranlib libv3test.a
touch testsuite_wchar_t
/export/home/dlsa/code/gcc-3.4.6/libstdc++-v3/scripts/create_testsuite_files \
  /export/home/dlsa/code/gcc-3.4.6/libstdc++-v3/testsuite `${PWDCMD-pwd}`
/bin/ksh: /export/home/dlsa/code/gcc-3.4.6/libstdc++-v3/scripts/create_testsuite_files: cannot execute
make[6]: *** [testsuite_files] Error 126

Can anyone help me understand what this means ?
Thanks
