In a gcc invocation, cc1 fails with a "Not a directory" error when compiling a
trivial file if there is a file (not a directory) named "lib" in the parent to
the working directory.
To recreate it:
bash-3.2# mkdir temp
bash-3.2# cd temp
bash-3.2# mkdir temp1
bash-3.2# touch lib
bash-3.2# cd temp1
bash-3.2# cat>utl1.c<<EOF
> void fun1(){}
> EOF
bash-3.2# gcc -c utl1.c
cc1: error: ../lib/gcc/i686-pc-linux-gnu/4.2.1/include: Not a directory
cc1: error:
../lib/gcc/i686-pc-linux-gnu/4.2.1/../../../../i686-pc-linux-gnu/include: Not a
directory
gcc was built as follows:
../gcc-4.2.1/configure --prefix=/usr\
--libexecdir=/usr/lib --enable-shared --enable-threads=posix\
--enable-__cxa_atexit --enable-languages=c,c++\
--disable-bootstrap
make
make install
when run verbosely, gcc produces the following output:
bash-3.2# gcc -c -v utl1.c
Using built-in specs.
