The build fails as follows:
...
rm -f libhistory.a
ar cr libhistory.a history.o histexpand.o histfile.o histsearch.o shell.o mbutil.o xmalloc.o
test -n "ranlib" && ranlib libhistory.a
Configuring in sim
loading cache .././config.cache
checking for gcc... (cached) $gcc -O2
checking whether the C compiler ($gcc -O2 -g -O2 ) works... no
configure: error: installation or configuration problem: C compiler cannot create executables.
*** Error code 1
make: Fatal error: Command failed for target `configure-sim'
Current working directory /net/cog/project/reb/src/base/gdb
*** Error code 1
The problem is that config.cache contains this line:
ac_cv_env_CC_value=$'gcc -O2'
Note the extra dollar sign. The problem is that Bash 2.05
is putting that dollar sign into config.cache. This is a
known problem in Bash 2.05; see
<http://mail.gnu.org/archive/html/autoconf/2001-10/msg00138.html>.
>How-To-Repeat:
configure --disable-nls
make CC='gcc -O2'
>Fix:
See attachment for a proposed fix to PROBLEMS.
