I am trying to create the shared library (.so) so that I can call it using .External command from R for the lassoshooting package:
https://cran.r-project.org/web/packages/lassoshooting/
Basically, I have downloaded the package source from the above website. However, when I go the the correct directory (.../lassoshooting/src) and use the command
R CMD SHLIB -o ccd_r.so ccd_r.c
I get the following error:
clang -dynamiclib -Wl,-headerpad_max_install_names -undefined
dynamic_lookup -single_module -multiply_defined suppress
-L/Library/Frameworks/R.framework/Resources/lib -L/usr/local/lib -o ccd_r.so ccd_r.o -L/Library/Frameworks/R.framework/Resources/lib

ld: library not found for -lgfortran
clang: error: linker command failed with exit code 1 (use -v to see invocation) make: *** [ccd_r.so] Error 1
Why is this happening?

I was trying to build this Then i get this error
$make
g++ -o rd_view -g -Wall libcs631.a rd_direct.o pnm_display.o -lm -lX11
ld: library not found for -lX11
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [rd_view] Error 1
I'm on m1 mac ventura. Any help will be appreciated. I tried installing libx11,Xquartz also.
You do not have libX11.a in your default library directories.
Locate (or/and install)it.
To install (ubuntu):
sudo apt-get install libx11-dev
To search
Use apt-file search [filename]
Location on my computer:
/usr/lib/x86_64-linux-gnu/libX11.a
As an additional remark: move your libcs631.a after all the object files as libraries are are searched only one time so all needed symbols have to be known to the linker before it searches the library.
So I've been trying to install the luasql-mysql module for a while now and I keep running into problems. This time when I go to install it gives me this error:
luasql-mysql 2.5.0-1 depends on lua >= 5.1 (5.3-1 provided by VM)

collect2.exe: error: ld returned 1 exit status

I'm going to try reinstalling everything and hopefully that works but if anyone knows why I'm getting this problem then I would appreciate the help.
I am not an experienced programmer/developer/software engineer, but I need to get this older version of guile-2.0.11 built "by hand" rather than using home-brew (which installs the latest version of guile). I downloaded the tarball for guile-2.0.11 from the GitHub repository, extracted it and ran the shell script autogen.sh. This produced a configure executable which ran to completion and generated a Makefile. When I run make, the build continues until I get the this error:
Undefined symbols for architecture x86_64:
"_clock_getcpuclockid", referenced from:
_scm_init_stime in libguile_2.0_la-stime.o
"_ffi_call", referenced from:
_scm_i_foreign_call in libguile_2.0_la-foreign.o
and 16 more "ffi" similar messages. Then the error messages finishes
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[3]: *** [libguile-2.0.la] Error 1
make[2]: *** [all] Error 2
make[1]: *** [all-recursive] Error 1
The linker apparently can't find these symbols. The explicit link command is quite extensive..it shows all the options, include and library paths if I use "make V=1". Here is the beginning, showing the options and paths:
Applications/Xcode.app/Contents/Developer/usr/bin/make all-am
/bin/sh ../libtool --tag=CC --mode=link gcc - I/usr/local/opt/gettext/include -I/usr/local/include - I/usr/local/opt/readline/include - I/usr/local/Cellar/gettext/0.19.8.1/include -D_THREAD_SAFE -Wall - Wmissing-prototypes -Wdeclaration-after-statement -Wpointer-arith -Wswitch- enum -fno-strict-aliasing -fwrapv -fvisibility=hidden - I/usr/local/Cellar/bdw-gc/7.6.0/include -g -O2 -L/usr/local/Cellar/bdw- gc/7.6.0/lib -lgc -L/usr/local/opt/libffi/lib -liconv - L/usr/local/opt/gettext/lib -lintl -R/usr/local/opt/gettext/lib -Wl,- framework -Wl,CoreFoundation -L/usr/local/lib -lunistring -R/usr/local/lib -version-info 29:2:7 -export-dynamic -no-undefined -L/usr/local/opt/gettext/lib -L/usr/local/lib -L/usr/local/opt/readline/lib -L/usr/local/Cellar/gettext/0.19.8.1/lib -o libguile-2.0.la -rpath /usr/local/lib
Then there is libtool.
libtool: link: gcc -dynamiclib -o .libs/libguile-2.0.22.dylib .libs/libguile_2.0_la-alist.o .libs/libguile_2.0_la-arbiters.o .libs/libguile_2.0_la-array-handle.o
and many many more xxxx.o
then
-Wl,-force_load,../lib/.libs/libgnu.a -L/usr/local/Cellar/bdw- gc/7.6.0/lib -lgc -L/usr/local/opt/libffi/lib -L/usr/local/opt/gettext/lib -L/usr/local/lib -L/usr/local/opt/readline/lib - L/usr/local/Cellar/gettext/0.19.8.1/lib -lintl -lunistring -liconv -lgmp - lltdl -lm -g -O2 -Wl,-framework -Wl,CoreFoundation -install_name /usr/local/lib/libguile-2.0.22.dylib -compatibility_version 30 - current_version 30.2 -Wl,-single_module
The up-to-date version of ffilib is in the symlink /usr/local/opt/libffi/lib which is in the ld path, so I would think that the linker could find it. Any help would be greatly appreciated.
This problem is really two problems: (1) the undefined symbol "_clock_getcpuclockid" and (2) all the "ffi" undefined symbols. The answer to the second problem is here and the answer to the first problem is here. There may be other solutions but these resulted in the installation of guile-2.0.11 on my macOS Sierra (10.12.5),
I use libwebsockets for a client program in C. Therefore I build the library for the libwebsocktes locally on my machine (ubuntu). After I want to Build the Project in Eclipse, I get the following output:

It seems to be a problem with the libwebsockets.a. But how I can solve it ?
I am trying to resurrect on old OpenGL program on a Linux Mint system. I installed freeglut3-dev using Synaptic Package Manager. The compiler does not complain about not being able to find the glut include file anymore, but now I have other problems:
cc -Wall -o gears main.c draw_gears.c gl_drawing.c load_data.c normal.c prep_data.c -lglut

Try this:
cc -Wall -o gears main.c draw_gears.c gl_drawing.c load_data.c normal.c prep_data.c -lglut -lGLU -lGL
