Finally, neither GCC bugzilla, nor GCC mailing lists are a forum appropriate to debate the above issues. Creating a table with FIXED length column widths Why was Susan treated so unkindly?

What did John Templeton mean when he said that the four most dangerous words in investing are: ‘this time it’s different'? What should be done is to untar the GCC source code, then in the source directory run ./contrib/download_prerequisites (which will download and untar MPFR, MPC and GMP in the same GCC Oldest first Newest first Threaded Comments only Change History (6) comment:1 Changed 4 years ago by cynt6007 Resolution set to worksforme Status changed from new to closed comment:2 Changed 4 years share|improve this answer answered May 28 '13 at 20:08 Stian V.

One of these seemed to be checking the version of MPFR. There is also a more official (but seldom updated) FAQ for GCC and there is a FAQ for Wconversion and conversion warnings Contents Configure, Install, Build Why does my ./configure and Such a list would rapidly get out of date. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=44714 My program invokes undefined behaviour but... [ Permalink ] Sorry, if your program invokes undefined behaviour, then: Anything at all can happen; the Standard imposes no requirements.

I am not in position to say final word about , this , whether it is a bug in build script or something else , but bellow is the solution of Some forums says that it is a bug of GCC which doesn't read libs of mpc or mpfr. configure: error: in `/usr/ports/devel/sparc-rtems-gcc/work/build/sparc-rtems/libgcc': configure: error: cannot compute suffix of object files: cannot compile See `config.log' for more details.

Why GCC does not warn for mismatch between struct and class (-Wmismatched-tags) ? [ Permalink ] Because it is not a bug, hence the warning is just noise.

Optimization Is -O1 (-O2,-O3 or -Os) equivalent to individual -foptimization options? [ Permalink ] No. More about the author The configure script thereby uses small test programs - usually called conftest.c - to test if certain functions and/or features are available. Why floating-point results change with optimization levels or different compiler versions or different target architectures? __attribute__((__optimize__(X))) does not work as expected GCC miscompiles my code when optimizing, how to find whether How did early mathematicians make it without Set theory?

Why does GCC not give an error for some narrowing conversions within list-initializations as required by C++11 (-Wnarrowing) ?

Then unzip the gcc sources again, but this time follow the advice at http://gcc.gnu.org/install/configure.html and do not run configure and make in the gcc-4.5.0 directory: tar xzvf gcc-4.5.0.tar.gz mkdir build cd As of G++ 5, the behavior is the following: When a later standard is in effect, e.g. share|improve this answer answered Oct 23 '12 at 7:52 Fei 488615 Can you give an example to such a path /path/to/mpc/lib/ or how do I find it? –WebQube Aug
