It might help if I had more idea what's supposed to happen. Was I supposed to define SEARCH_DIR? Or replace it? Is that 1 line or 2?
Just running ld --verbose | grep SEARCH_DIR | tr -s ' ;' \\012 ld: fatal error: no input files Trying as 1 line: ld --verbose | grep SEARCH_DIR | tr -s ' ;' \\012 make VERBOSE=1 tr: extra operand ‘make’ Try 'tr --help' for more information. ld: fatal error: no input files From the stackoverflow example, if I put "-Wl,--verbose" in my CMakeCache.txt as part of the string that gets passed to the C compiler would that do it? If I could use a more normal -L and -l I'd be more comfortable but I'm working through the full cmake process. I don't know how to extract what I need to try to link this manually. Yup, aarch64 on an Odroid N2: Linux odroid 4.9.177+ #1 SMP PREEMPT Sat May 18 09:49:10 CEST 2019 aarch64 GNU/Linux Debian from meveric's image, still Stretch so far. Some dependencies I built from source, some are from the debs if they were new enough. I disabled GR-WAVELET, FEC and GR-DTV, got it to build. Ran volk_profile, it picked up the neon correctly. I don't have an RF source driver so far. Using an RTL2832 dongle, trying to build Osmocom. There's a ton of obsolete documentation out there. Probably doesn't matter but my LD_LIBRARY_PATH is /usr/local/lib:/lib:/lib/aarch64-linux-gnu:/usr/lib:/usr/lib/aarch64-linux-gnu On 9/6/19, Vasil Velichkov <vvvelich...@gmail.com> wrote: > Hi Alen, > > On 06/09/2019 00.45, Alan Corey wrote: >> I think this is a low level problem, it gets through cmake and all >> that, but when it gets down to make and ld I get: >> >> [ 49%] Built target fft_qa_fft_shift >> [ 49%] Linking CXX shared library libgnuradio-filter.so >> /usr/bin/ld: error: cannot find -lgsl >> /usr/bin/ld: error: cannot find -lgslcblas >> collect2: error: ld returned 1 exit status >> gr-fec/lib/CMakeFiles/gnuradio-fec.dir/build.make:824: recipe for target >> 'gr-fec >> /lib/libgnuradio-fec.so.3.9.0.0-git' failed >> make[2]: *** [gr-fec/lib/libgnuradio-fec.so.3.9.0.0-git] Error 1 >> CMakeFiles/Makefile2:4691: recipe for target >> 'gr-fec/lib/CMakeFiles/gnuradio-fec >> .dir/all' failed >> make[1]: *** [gr-fec/lib/CMakeFiles/gnuradio-fec.dir/all] Error 2 >> make[1]: *** Waiting for unfinished jobs.... >> [ 52%] Built target gnuradio-filter >> Makefile:140: recipe for target 'all' failed >> make: *** [all] Error 2 > > Post the output of > > ld --verbose | grep SEARCH_DIR | tr -s ' ;' \\012 > make VERBOSE=1 > >> Yet ldconfig -p | grep gsl says >> libgslcblas.so.0 (libc6,AArch64) => /usr/local/lib/libgslcblas.so.0 >> libgslcblas.so (libc6,AArch64) => /usr/local/lib/libgslcblas.so >> libgsl.so.25 (libc6,AArch64) => /usr/local/lib/libgsl.so.25 >> libgsl.so (libc6,AArch64) => /usr/local/lib/libgsl.so > > The ldconfig cache is used only by the runtime linker and is not used when > you build a program or library, e.g. not used by /usr/bin/ld. > https://stackoverflow.com/a/21610523/2315085 > >> What's maybe odd is that ls -al | grep gsl in /usr/local/lib looks like >> this: >> -rw-r--r-- 1 root staff 22783350 Sep 3 21:19 libgsl.a >> -rw-r--r-- 1 root staff 1885346 Sep 3 21:19 libgslcblas.a >> -rwxr-xr-x 1 root staff 949 Sep 3 21:19 libgslcblas.la >> lrwxrwxrwx 1 root staff 20 Sep 3 21:19 libgslcblas.so -> >> libgslcblas.so.0.0.0 >> lrwxrwxrwx 1 root staff 20 Sep 3 21:19 libgslcblas.so.0 -> >> libgslcblas.so.0.0.0 >> -rwxr-xr-x 1 root staff 1121320 Sep 3 21:19 libgslcblas.so.0.0.0 >> -rwxr-xr-x 1 root staff 918 Sep 3 21:19 libgsl.la >> lrwxrwxrwx 1 root staff 16 Sep 3 21:19 libgsl.so -> >> libgsl.so.25.0.0 >> lrwxrwxrwx 1 root staff 16 Sep 3 21:19 libgsl.so.25 -> >> libgsl.so.25.0.0 >> -rwxr-xr-x 1 root staff 12949992 Sep 3 21:19 libgsl.so.25.0.0 >> >> Only the symlinks to the real files end up in the ld.so cache, >> ldfonfig doesn't pick up the actual files (libgsl.so.25.0.0 and >> libgslcblas.so.0.0.0) at all.
