[mpich-discuss] mpich-3.1.4 compilation fails on cygwin 1.7.35

[Lucian Anton]

I tried to compile mpich-1.1.4 on cygwin 1.7.35 with the following
configure flags:

$ gcc --version
gcc (GCC) 4.9.2

 ./configure --prefix=/home/lanton/Apps/mpich-3.1.4-install
--enable-fortran=yes --with-pm=gforker --enable-threads=serialized
--enable-romio --disable-cxx  --enable-static --disable-shared


make fail with following error message:

----

To avoid the weak aliases I have tried builds with configure CPPFLAGS set
to -DHAVE_PRAGMA_WEAK or -DHAVE_PRAGMA_HP_SEC_DEF.
In this case the sources are compiled by the link fails because of
unresolved symbols.


Any hint would be much appreciated,
