Hi,
this is my first mail on the mailing list, so please excuse any mistakes.
I am trying to compile GCC 4.6.1 on my Cygwin 1.7.14 following this:
http://cygwin.wikia.com/wiki/How_to_install_a_newer_version_of_GCC
I downloaded and installed every package needed (GMP, MPFR,
Multiprecision).
Then I went into my build folder and typed
../gcc-4.6.1/configure --enable-languages=c,c++ --enable-libgomp
--with-multilib-list=m64,m32 --prefix $HOME/gcc64pls --program-suffix
-64pls
(I need OMP and 64 bit support as my programs need more than 2 gb RAM!)
That worked fine, but just for completeness, I attached the output as
"confout.txt".
Now I try to build GCC with "make -j4". Here the problem occurs: The
data cannot be moved from "gcc" to "stage1-gcc" (Permission denied).
After this error I checked the build folder and saw that the
corresponding folder is not there. Then I tried to manually add all
folders necessary, but it seems that they get deleted during build
progress (saw some rm -r in Makefile). So I get exactly the same
problem after manually adding all folders.
I wanted to attach the full output as well, but the file size with
>800kb seemed to be too big. I just attached the last 10-20%, but of
course I can send the other output as well.
Additionally, I attached my version information in "cygcheck.txt".
Currently, I just dont know what to do. I tried to find some help via
Google or the archive, but it seems that I am the only one facing this
exact problem.
Any (general) advice? Thanks!
Ignore the wikia article. Third party "advice" on how to use cygwin is
usually outdated and/or flat out wrong. The multilib thing is especially
suspicious, given that cygwin is *not* 64-bit capable.
I'd follow the directions at gcc's site, or -- even better -- invoke
`/usr/bin/gcc -v' and copy its known-good configure line. I've compiled
many versions of gcc with many versions of cygwin that way without
difficulty.
