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)

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 have been trying to install and execute a c-program using fftw3 library on Ubuntu machine but getting this error so many times.
How to fix the error? Help is much appreciated.

Hey I am currently learning C and tried to divide my code in multiple files. But when it comes to compile the project, I got this error :
mingw32-gcc.exe -Wall -g -c D:\IDE\CodeBlocks\Projects\Tuto\main.c -o obj\Debug\main.o
mingw32-g++.exe -o bin\Debug\Tuto.exe obj\Debug\dico.o dico.h.gch obj\Debug\main.o
dico.h.gch: file not recognized: File format not recognized
collect2.exe: error: ld returned 1 exit status
I tried to clean and/or rebuild my project but nothing goes through this issue. Can anyone help me please ??
dico.h.gch is a precompiled header. You aren't supposed to link it with your objects. Remove it from the line that creates Tuto.exe.
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:
14:58:40 **** Incremental Build of configuration Build (GNU) for project ClientA ****
make all

It seems to be a problem with the libwebsockets.a. But how I can solve it ?
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: warning: directory not found for option '-L/usr/local/lib/gcc/x86_64-apple-darwin13.0.0/4.8.2'
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 am attempting to compile a C program with multiple files on window platform. However, when I make it, errors are occurred. I have already tried to modify command in makefile but still could not fix it.
This is my GCC command:
gcc -o "SYSMONTR" $(OBJPATH)/chkdsksp ../chkdsksp.c -g -I"$(DB2PATH)/include" -I"$(MYLIBDIR)" $(MYIQDIR)/iqclilib.a $(OBJPATH)/icrou.a -lc -ldb2 -lnsl -L"$(DB2PATH)/lib"
This is result:
gcc -o "SYSMONTR" ../../iLINKOBJ/chkdsksp ../chkdsksp.c -g -I"C:/Program Files/IBM/SQLLIB/include" -I"../../iLINKCLIB" ../../iLINKIQOBJ/iqclilib.a ../../iLINKOBJ/icrou.a -lc -ldb2 -lnsl -L"C:/Program Files/IBM/SQLLIB/lib"
../../iLINKOBJ/chkdsksp: file not recognized: File format not recognized
collect2: error: ld returned 1 exit status
makefile:49: recipe for target `SYSMONTR' failed
make: *** [SYSMONTR] Error 1
What could cause such error and what should I do with it? Using cygwin on Window (IDE: Eclipse).
Any supports will be appreciated.
If chkdsksp is an object file built by another team to run on AIX, you cannot expect it to function -- or even be recognized by your compiler -- on Cygwin. You must contact that team and get a) the source code or b) a version of the object file compiled for your platform (and tested).
