[COIN-DISCUSS] Problems with MPI application using COIN

[YANG YUAN]

Hi Andreas,

I tried icpc and icc. When compiling COIN without -cxxlib-gcc, the following
error comes out during the compilation:


CglProbing.cpp(41): error: name must be a namespace name
  using namespace __gnu_cxx;
                  ^

CglProbing.cpp(128): error: hash_set is not a template
    hash_set<OsiRowCut2  , row_cut_hash, row_cut_compare> rowCut_;
    ^

CglProbing.cpp(147): error: identifier "hash_set" is undefined
        hash_set<OsiRowCut2 , row_cut_hash,
        ^

CglProbing.cpp(147): error: type name is not allowed
        hash_set<OsiRowCut2 , row_cut_hash,
                 ^

CglProbing.cpp(147): error: type name is not allowed
        hash_set<OsiRowCut2 , row_cut_hash,
                              ^

CglProbing.cpp(148): error: type name is not allowed
          row_cut_compare>::iterator find;
          ^

CglProbing.cpp(148): error: the global scope has no "iterator"
          row_cut_compare>::iterator find;
                            ^

......

If i compile it with CXXFLAGS="-cxxlib-gcc", the COIN libraries can be
successfully compiled and installed. However, when i try to link my own MPI
program with COIN, without -cxxlib-gcc as a link option, the following error
comes up:

/home/osu4502/Coin-Cbc/lib/libCbc.so: undefined reference to
`std::__default_alloc_template<true, 0>::allocate(unsigned)'

......

After adding -cxxlib-gcc as a link option, my program compiles and links to
COIN successfully. but when i run the executable, again without printing out
the first line of main function, it directly gives me a seg fault.

Could you please help me to solve this problem?

Many thanks -- yang
