Logfiles, version output and patch
Hello there.
I am trying to compile GCC 6.5.0 with GCC 5.5.0 for Solaris 10 ('uname -a':
"SunOS Blade 5.10 Generic_141444-09 sun4u sparc SUNW,Sun-Blade-100") on a SPARC
machine (a Blade 100) and it fails by the linker error message of: "ld: fatal:
file elf64_sparc: open failed: No such file or directory". The only place on
the net i found this error message is another GCC bugticket - namely #30819 -
but the solution there did not work for me.
GCC 5.5.0 and Binutils 2.26 are installed from the OpenCSW repository. (Version
info has been attached.) Before running './configure', i had set
'$CONFIG_SHELL' by 'export CONFIG_SHELL=$SHELL' just as told in the other
bugticket. The shell is 'bash' 5.2.26 from the OpenCSW repository. It is set as
the default shell in '/etc/passwd' and it is in the envvar '$SHELL'.
The following './configure' command was issued from the directory '/gcc6':
'../gcc-6.5.0/configure --prefix=/opt/gcc6 --build=sparc-sun-solaris2.10
--with-gnu-as --with-gnu-ld --enable-shared --disable-nls
--enable-languages=c,c++,objc'
GCC6 source had to be modified a bit to be able to compile it, because the
macros 'NAN' and 'INFINITY' are resolved to functions on Solaris. (Long story,
please check [https://github.com/python/cpython/issues/136006] for details, if
seems relevant to the matter at hand.) Patch is attached. (Although due to the
simplicity of the modification, patching is not really necessary: just open
'libiberty/floatformat.c' and change 'NAN' to 'NAN("0x7fc00000")' and
'INFINITY' to 'INFINITY()'.)
Also attached the outputs of './configure' and 'make' and attached the logfile
'config.log'.
I am not sure if this is my fault or a bug and if it is, then which component's
bug it is; Binutils, GCC itself, shell, etc...
Please tell me if anything else is needed to be provided.
