Tobias,

Thanks for your quick reply.

Indeed, g++ is missing:

% configure:6851: checking command to parse nm output from gcc object
% configure:6956: g++ -c -O2 -I/usr/include -I/usr/include conftest.cpp >&5
% ./configure: line 6957: g++: command not found
% configure:6959: $? = 127
% : failed program was:
% #ifdef __cplusplus
% extern "C" {
% #endif
% char nm_test_var;
% void nm_test_func(){}
% #ifdef __cplusplus
% }
% #endif
% int main(){nm_test_var='a';nm_test_func();return(0);}
% configure:6956: g++ -c -O2 -I/usr/include -I/usr/include conftest.cpp >&5
% ./configure: line 6957: g++: command not found
% configure:6959: $? = 127
% : failed program was:
% #ifdef __cplusplus
% extern "C" {
% #endif
% char nm_test_var;
% void nm_test_func(){}
% #ifdef __cplusplus
% }
% #endif
% int main(){nm_test_var='a';nm_test_func();return(0);}
% configure:7056: result: failed

I don't know the background about using g++ for this test, probably
because of C++ symbol name mangling.  Anyway given that
"global_symbol_pipe" is mandatory, I'm little bit surprised that the
configure script doesn't fail loudly.

I guess the only solution is to install g++?

Thanks.
