So I have tried the MinGW-5.0.3.exe in Wine, but it tries to install from some wrong url and it fails to install. I have unpacked the tarballs by hand into "~/.wine/drive_c/MinGW": binutils-2.17.50-20070129-1.tar.gz w32api-3.7.tar.gz gcc-g77-3.4.5-20051220-1.tar.gz gcc-g++-3.4.5-20051220-1.tar.gz gcc-core-3.4.5-20051220-1.tar.gz mingw-runtime-3.10.tar.gz also in the same directory, I had to do: cp ../windows/system32/msvcr90.dll lib/ Also I've added the bin directory to PATH using the following trick: $ cat > tmp <<EOF REGEDIT4 [HKEY_CURRENT_USER\Environment] "PATH"="C:\\\\MinGW\\\\bin" EOF $ wine regedit tmp Then I build and installed numpy using: wine "C:\Python27\python" setup.py build --compiler=mingw32 install And now there is no segfault when constructing a complex array! So newer (newest) mingw miscompiles NumPy somehow... Anyway, running tests, it gets much farther then before, now it hangs at: test_multiarray.TestIO.test_ascii ... err:ntdll:RtlpWaitForCriticalSection section 0x785b7428 "?" wait timed out in thread 0009, blocked by 0000, retrying (60 sec) fixme:keyboard:X11DRV_ActivateKeyboardLayout 0x4090409, 0000: semi-stub! err:ntdll:RtlpWaitForCriticalSection section 0x785b7428 "?" wait timed out in thread 0009, blocked by 0000, retrying (60 sec) err:ntdll:RtlpWaitForCriticalSection section 0x785b7428 "?" wait timed out in thread 0009, blocked by 0000, retrying (60 sec) ... Not sure what this problem is yet. Ondrej _______________________________________________ NumPy-Discussion mailing list [email protected] http://mail.scipy.org/mailman/listinfo/numpy-discussion
