I have to do a compiler with flex and bison for a school project.
They give to me example of new language but I can't compile them..
The code is working fine for other people so the problem come from my Mac. The problem appears when I try to compile with make command, he say "ld: library not found for -lglib-2.0".
I installed "Glib" already but this don't solve the problem.
make
[ 20%] Linking C executable facile
ld: library not found for -lglib-2.0
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[2]: *** [facile] Error 1
make[1]: *** [CMakeFiles/facile.dir/all] Error 2
make: *** [all] Error 2
I need to compile the code to work after on the project.
Thanks you

I get the following error while compiling xpdf using make. I've tried using the command:
LIBS=-lm make
However, it doesn't work. I know the problem is that the c compiler cannot recognise the math symbols in the source code because the math library is not available to it, but I don't know how to fix it.

I realised I had to use the g++ compiler instead of gcc after reading the man page for gcc which stated:
The usual way to run GCC is to run the executable called gcc, or
machine-gcc when cross-compiling, or machine-gcc-version to run a
specific
version of GCC. When you compile C++ programs, you should invoke GCC as g++ instead.
I am making some tutorial exercises for school practice in c. I have this little method(Heron's formula):
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
.
.
double s = (a+b+c)/2.0;
double A = sqrt(s*(s-a)*(s-b)*(s-c)) //a,b,c = 3,3,2
.
.
I can compile it with a gcc:
gcc exercise.c -o exercise -lm
Everything works well. Problem is, when i try to rewrite the same code in Netbeans, it throws this error:

In Netbeans, sqrt() method only works with a number (sqrt(2.5)), but not with a constant (sqrt(s)). I think, it is some problem with a Netbeans compiler. Do anyone have some similar issue?
I found one solution. If you have the same problem, you can hard link a math.h in NetBeans IDE:
File->Project Properties->Build->Linker->Libraries->add Library/add standard Library
I also tried add an -lm argument to NetBeans compilator configuration, but this isn't worked.
I'm totally new to cmake. After an svn update (but also to binutils and I suspect this is causing the problem), I get an error (I successfully compiled and used the program before)

Maybe it's related to this Fedoraproject DSO Change?
I have an up-to-date archlinux (binutils-2.23-1).
I tried to edit lines in the ccmake . menu. After hitting [c] the original options are restored (so I cannot add /usr/lib/libgfortran.so.3 to the GMSH_EXTERNAL_LIBRARIES variable in order [g] generate the new Makefiles).
I also tried adding some options which were recommended in the cmake irc chat, but it eventually didn't work.
cmake . -DCMAKE_LINK_FLAGS=-Wl,--add-needed
or
cmake . -DCMAKE_LINK_FLAGS=-lgfortran
Resulting in the same error. What can I do?

To add a library to the link command, you can use target_link_libraries. Apparently in this case you want:
target_link_libraries(gmsh ${LINK_LIBRARIES} gfortran)
While compiling glibc 2.11, I get the following error. Any idea how to solve this.

Apparently, this is a known problem with building glibc on Ubuntu. In essence:
glibc does not build with _FORTIFY_SOURCE enabled, and Ubuntu compiles stuff with -D_FORTIFY_SOURCE=2.
You need to disable this by undefining _FORTIFY_SOURCE. i.e. append -U_FORTIFY_SOURCE to your CFLAGS.
I added a third party library to my code and is getting errors like this when running make. Please help me understand this error.

Those are Linking errors, which tell you the linker cannot find definitions for the library you are using.
You will have to link the library to your project.
gcc <your files for compilation> -lLibName
Read this for better understanding.
I still get the error even if
readline library is installed and
-lreadline is added to gcc compiling command.
The root cause of my issue is the order of the libraries/code: -lreadline (and other libraries) should be put right before -o options.
