jack-rack compilation error

[Susie B.]

Hi there,

I tried to install Jack Rack 1.4.7 from Sourcery, but it failed with the following error.

Code: Select all

/usr/bin/ld: jack_rack-midi.o: undefined reference to symbol 'pthread_create@@GLIBC_2.2.5'.
/usr/bin/ld: /lib64/libpthread.so.0: error when adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit state
make[2]: *** [Makefile:356: jack-rack] Error 1
make[1]: *** [Makefile:281: all] Error 2
make: *** [Makefile:306: all-recursive] Fatal error 1

I have searched the internet for solutions to these errors and read them, but they were too technical for me to understand.

I would appreciate any information on how to fix these errors.

Thanks in advance.
Susie B.

I tried to install Jack Rack 1.4.7 from Sourcery, but it failed with the following error.

I forgot to mention the version of my Salix .
I did it on Salix64 15.0.

Are you sure about that? Sourcery has been removed from Salix 15.0.

Hi Gapan,

Are you sure about that? Sourcery has been removed from Salix 15.0.

I got it from the Slackel repository and installed it manually on Salix 15.0.
(I'm not very good at the command line, so...)

Jack-rack builds and installs without issues here on 15.0 using slapt-scr and the slapt-src repository set to the Slackbuild repository.

Code: Select all

rich[~]$ cat /etc/slapt-get/slapt-srcrc 
BUILDDIR=/usr/src/slapt-src
PKGEXT=txz
#SOURCE=http://slackware.uk/salix/slkbuild/15.0/

Hi laprjns,

Thank you for your taking the time and reply.

I have tried using the slapt-src and slackbuilds.org repositories as advised, but get seemingly same error.

I also got the Jack Rack 1.4.7 source from SourceForge and manually did configure and make, but it still gave the same error.

I also got the Jack Rack 1.4.7 source from SourceForge and manually did configure and make, but it still gave the same error.

Out of curiosity I tried to compile it myself and I also got the complain about undefined reference to pthread ... (then to libdl and and finally to libm)
If no one will give the proper solution, here is a workaround

- do ./configure
- do make
- all files should be compiled, just linking process should give the above undefined reference, so go into directory "src" and issue this:

Code: Select all

gcc  -g -O2   -o jack-rack -ljack -lgtk-x11-2.0 -lgdk-x11-2.0 -lpangocairo-1.0 -latk-1.0 -lcairo -lgdk_pixbuf-2.0 -lgio-2.0 -lpangoft2-1.0 -lpango-1.0 -lgobject-2.0 -lglib-2.0 -lharfbuzz -lfontconfig -lfreetype    -lasound -lxml2 -lpthread -ldl -lm jack_rack-midi_window.o jack_rack-midi_control.o jack_rack-wet_dry_controls.o jack_rack-file.o jack_rack-midi.o jack_rack-util.o jack_rack-plugin_settings.o jack_rack-process.o jack_rack-plugin_desc.o jack_rack-plugin_mgr.o jack_rack-ui.o jack_rack-plugin.o jack_rack-port_controls.o jack_rack-plugin_slot.o jack_rack-jack_rack.o jack_rack-lock_free_fifo.o jack_rack-ui_callbacks.o jack_rack-plugin_slot_callbacks.o jack_rack-control_callbacks.o jack_rack-main.o

Nice workaround jury, thanks!

I have now uploaded packages to our extra repo. Give it some time for the mirrors to sync and you should be able to get it with slapt-get/gslapt.

Hi jury.

I was also able to successfully compile Jack Rack using your workaround.
I installed it as well and it seems to work fine.
I appreciate you taking the time to help me.

Hi gapan.

I appreciate you adding the Jack Rack binary package to the Salix repository.
It is easier for a layman like me to use the official package than building it by myself.
I will install it as soon as the package arrives in the mirror.
