Question

I try to compile an application with kdevelop 3.5.4 on Ubuntu 10.04, but it fails with the following errors:

checking whether make sets $(MAKE)... yes
checking for g++... g++
checking whether the C++ compiler works... no
configure: error: in `/home/nts/wktools4':
configure: error: C++ compiler cannot create executables
See `config.log' for more details.
*** Exited with status: 77 ***

config.log:

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by configure, which was
generated by GNU Autoconf 2.65.  Invocation command line was

I have no idea what’s wrong. Could it be a version mismatch of the used tools?

Answer 1

Your LDFLAGS environment variable ends with –lm instead of -lm (i.e. you used a unicode dash instead of the ASCII dash), so instead of finding the math library, your compiler tries to load a file named –lm and complains with g++: –lm: No such file or directory.
