[mpich-discuss] question about running mpich2 on sol86

[Shangli Wu]

I try to build the code with CC, it got link errors on sol86. I can
build and run cpi.c using same makefile without problem (on sol86).
 
chfcsx023:/home/shangliw/libraries/mpich2-1.0.8p1/examples/testcase_1 >
make
@------------------------------------------
@=== Loading ./ems0.exe:   CC ...
Undefined               first referenced

void MPI::Init(int&,char**&)            ./cxxpi.o
MPI::Datatype::__vtbl           ./cxxpi.o
[Hint: try checking whether the first non-inlined, non-pure virtual
function of class MPI::Datatype is defined]
 
ld: fatal: Symbol referencing errors. No output written to ./ems0.exe
*** Error code 1
clearmake: Error: Build script failed for "ems0.exe"
 
 
Any suggestion?
 
Thanks

	You need to specify the directory containing the C++ compiler
libraries in the environment variable LD_LIBRARY_PATH or build MPICH2
without shared libraries. (The default build is without shared
librares.)
	 
	Also try compiling and running a simple C++ program directly
with the C++ compiler, not mpicxx.

		Hi,
		 
		I try to build/run the example cxxpi.cxx on Sol86 using
mpicxx. Compile seems OK. But when I run it, it shows error as:
		 
	
chfcsx023:/home/shangliw/libraries/mpich2-1.0.8p1/examples/testcase_1 >
mpicxx cxxpi.cxx

		ld.so.1: a.out: fatal: libstdc++.so.5: open failed: No

		The same file can build/run on Sun4v/Linux without any
problem. Would someone help me to understand what's wrong on Sol86?
		 
		Thanks
