ppl "remainder bug" checking on mingw targets
Hi,
I am trying to compile ppl for x86_64-w64-mingw32, for gcc. Is it normal for the "checking if the compiler has the remainder bug..." takes very long? Is there a way to bypass this check in order to speed up compilation?
Thanks!
Ruben
PS: using ppl-0.11 and TDM64 GCC 4.5.1

Hello.
Never tried on that configuration, but I see no reason why it should take long. What exactly are you observing? Could it be that the time is actually spent doing something else?

I do not recommend bypassing it.
Enea.
Thanks!

I can see in my task manager that conftest.exe is running, using 50% of my
dual core continually.
After I kill the conftest process, configure continues (thinks it has found the bug) and make fails on some error (deleted the build directory... if you want I can retry and help fix it).

Try commenting out the following line in configure.ac # AC_CXX_HAS_REMAINDER_BUG and see if the time spent drops down.
Note: this is NOT a solution. It is just a test to see if that check is the real cause of what you are observing.

I have localized the problem: TDM64 GCC causes the conftest.exe to run forever/"a very long time". If I use another build of the toolchain by someone else, the program crashes (which is an indicator of the bug, as I have already read somewhere).
I will take it up with TDM himself. Thanks for the help.
I am now trying to compile ppl with a trusted compiler (sezero's private build from mingw-w64.sourceforge.net) and came accross this error:

Unless you know a fix, I will take this and any other errors to the mingw-w64 mailing list and recontact you when I have all the necessary fixes.

I am now trying to compile ppl with a trusted compiler (sezero's private build from mingw-w64.sourceforge.net) and came accross this error:
The cause of the error is located: the mingw-w64 headers used the assumption that "restrict" is a keyword in C++ (but it is only a keyword in C99), and defined something accordingly (don't know what exactly). All the references in the error message are to a member function named "restrict", which was problematic. "restrict" is a keyword in C99, but as ppl is C++, it should be ok (as long as the std doesn't add it later).
The mingw-w64 headers have been changed to remove the problem (patch is underway).
Additionally, unlike mpfr and mpc, which detect automatically if GMP has been built statically and/or dynamically, ppl does not, and I had to add "--disable-shared" to my configure arguments for ppl. Is there a way to mimic the mpfr and mpc behavior to autodetect this? Thanks.
I have also run "make check", which passes all tests on x86_64-w64-mingw32 (this is with ppl release 0.11 and GCC 4.4.5 (prerelease dated 20100912) built from MSYS).
