#26 fixed Configuration incorrect in Data directory with VPATH build and -mno-cygwin somebody tkr
Description

When you configure the Data project in CYGWIN with the -mno-cygwin option and a VPATH build, soft links are created from the files in build_dir/Data/*/* to the files in src_dir/Data/*/*, but these softlinks cannot be understood by an executable that is compiled with the -mno-cygwin flag, since soft links don't exist in Windows. Furthermore, it seems that even if the configuration was ostensibly done with --enable-gnu-packages, the executables do not infact get linked with bzlib and other GNU libraries, since these also do not exist in Windows.

#110 worksforme Couenne does not compile with gcc 4.7.2 stefan fmargot
Description

Hi:

After doing a V_PATH configuration et compiling couenne-trunk with gcc version 4.7.2 20121109 (Red Hat 4.7.2-8) (GCC) on Fedora release 18 (Spherical Cow) using:

../configure -C make install

I get: ClpSimplexDual?.o In file included from ../../../Clp/src/ClpConfig.h:28:0,

from ../../../Clp/src/ClpModel.hpp:9, from ../../../Clp/src/ClpSimplex.hpp:16, from ../../../Clp/src/ClpSimplexDual.hpp:14, from ../../../Clp/src/ClpSimplexDual.cpp:101:

./config.h:85:0: error: "HAVE_CMATH" redefined In file included from ../../../Clp/src/ClpSimplexDual.cpp:100:0: ../../../Clp/src/ClpHelperFunctions.hpp:10:0: note: this is the location of the previous definition

The only fix I could find is to modify Clp/src/config.h as follows:

#ifndef HAVE_CMATH #define HAVE_CMATH 1 #endif Francois
