Can you successfully build and run a simple test program that loads ldqnx.so but does not link with nlopt? If not, then it's not an nlopt problem. Does the board have a test suite you can run to verify programs built in Cygwin work properly?
Have you tried building nlopt as a static lib and linking with that?

The board has an ARM Cortex-A8 processor. Did anybody cross-compile the NLopt library for QNX on BBB or a similar board with ARM processor? Up to now I did following steps to configure and build the library: 1. Created a new QNX C Project in Momentics 2. Configured the Makefile by running <code>./configure --without-octave --without-python --without-guile --enable-shared --host=arm-unknown-nto-qnx6.5.0 --build=i486-pc-nto-qnx6.5.0 CC="qcc -V4.4.2,gcc_ntoarmv7le" CPP="qcc -V4.4.2,gcc_ntoarmv7le -E" CXX="QCC -V4.4.2,gcc_ntoarmv7le" CXXCPP="QCC -V4.4.2,gcc_ntoarmv7le -E" LD="arm-unknown-nto-qnx6.5.0-ld" NM="arm-unknown-nto-qnx6.5.0-nm -B"</code> within Cygwin environment. 3. Run "Build Project" in Momentics The build process succeed, but if I want to use the library within another Project the execution fails with the message: Process 36886 (nlopt_test_ctschmidt138926111541656) terminated SIGBUS code=1 fltno=5 ip=01024c34(/usr/lib/ldqnx.so.2@_band_get_aligned+0x168) mapaddr=00024c34. ref=bee2e36a Does anybody know what I'm doing wrong? Does anybody has an idea where the fault could be located?
