Build error on 'make tests' for synthetic target

[Michael Bergandi]

Gentleman,

I am trying to use the synthetic target to do some testing of a
package I am working on. My package has some tests that I would like
to build, but I haven't figured out how to build only the tests for it
and not everything else. If someone could provide some guidance on
that, that would be great.

In the mean time, I tried to just build all of the tests and the build
errored out with the following:

make -r -C infra/current tests
make[1]: Entering directory `/home/mike/ecos-cvs/synthbuild/infra/current'
gcc -L/home/mike/ecos-cvs/synthbuild/install/lib -Ttarget.ld -o

I am running on Ubuntu 10.04.1 LTS. Here is some config info:

Has anyone else attempted building the tests on the synthetic target
or figure out what to do with the error above?

This looks like a build issue related to your Linux distro. Please raise
a bug report at http://bugs.ecos.sourceware.org and include the above
error message plus the output of "gcc -v" and "uname -a".

Thank you

Yes, I can confirm it, this bug exists (not only for Ubuntu). Today, I
use two temp. "solutions", either

i. I do not make 'cxxsup' test at all

  % make -s tests IGNORE_LINK_ERRORS=y ;# only 1 test cannot be built!

or

ii. I have installed GCC-4.3 *in parallel*

  % sudo aptitude install gcc-4.3 g++-4.3 ;# this won't ruin your box

and with that GCC I can build all tests

  % make -s CC=gcc-4.3 && make -s CC=gcc-4.3 tests ;# all should pass
