[petsc-users] Problem in compiling PETSc+ML

[Satish Balay]

Here is one way to get --download-ml working. [its a bit hakey]

1. update ml.py to run configure with additional options: "--disable-libcheck FLIBS=Ws2_32.lib"

diff --git a/config/BuildSystem/config/packages/ml.py b/config/BuildSystem/config/packages/ml.py

       self.framework.popLanguage()
     else:
       args.append('F77=""')

2. run configure with option CPPFLAGS=-DICL [this works arround some include file issues inside ML]

Here ML gets successfully built  - but its built as libml.a - not libml.lib

3. copy PETSC_ARCH/lib/libml.a to PETSC_ARCH/lib/libml.lib

4. rerun previous configure command [don't forget CPPFLAGS=-DICL option]
