please help me
w64xmmtest should only be used on Windows. I think you used configure --enable-xmm-clobber-test on Linux. Don't do that.

I am trying to build a project with this dune file:

But am getting the error:

Could anyone point me in the right direction?
Thanks :)
Do you have the libz available on your system ? it looks like the ld linker does not find it in its search path.
libz.a is a C library that implements C function for compressing/decompressing data. Such libraries come with your OS distribution independently of Ocaml.
Ocaml tooling provides way to use C library (via stub) using ld (the standard linker) that will link your ocaml stubs to the functions of libz.a . But if the required library is missing, you get the error you quoted.
-lz is saying to ld to link your application with the libz.a (or libz.so) library that is usually located in /usr/lib - if libz.a (libz.so) is not there, the linker will fail causing the emission of the following message :
/usr/bin/ld: cannot find -lz
collect2: error: ld returned 1 exit status
I'm very new to c++ (my background is in python and java) and I'm trying to build the cockroachdb project on a raspberry pi. To build I ran the command make build -j1.
However I am getting the error below:

Can someone help out a c++ beginner? Thank you.
apparently the issue has been around for a while. Workaround is to give -DDISABLE_GEOS_INLINE=ON as described on that page.
The respective switch is named differently on the GEOS Website though, yet that seems to be outdated information and does not work.
when i update gcc 4.1 to gcc 5.1
i want to use occi11.2 connect to oracle11g
and have install

how to deal with ?
I have a project (not mine) which I want to build. It has c++ and Python modules, which has to bind. When I launch cmake, I get this error:
/usr/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/4.8/../../../../lib/libantlr.a(BitSet.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object; recompile with -fPIC

I install antlr library with apt-get, and as I understand, I should recompile this library, but I have no idea in which part of source code of antlr library I should put -fPIC, or is there another way?
In Ubuntu 14.10 I have package libantlr-dev, which contains libantlr.a as well as libantlr-pic.a. I believe you have to use latter one, it is compiled with PIC
I have the following problem. On my Ubuntu I try to build a project and receive the following linker error(s) so far:
/usr/bin/ld:

I'm running under ubuntu 13 desktop, GCC 4.8, boost ver. is 1.54. As an IDE I'm working with
is the KDevelop.
I can provide any additional info about this issue if needed, but now I'm stuck with
this linking problem.
Any ideas?
Thanx in advance.
add_definitions only adds inputs for the preprocessor, which is in action even before the compiler starts its business and even much farther away from linking the executable, the step ld is supposed to be doing.
What you want to have ld resolve link-time dependencies is the CMake command target_link_libraries, which, for a given target, add a number of libs to link against after compilation.
In you case, the appropriate invocation could look like this
target_link_libraries(${PROJECT_NAME} [...] -lpthread [...]) #obviously without the '[...]' and the correct target name
I had a similar problem but with mpich. Both:
target_link_libraries(${PROJECT_NAME} [...] -lmpich [...])
and
target_link_libraries(${PROJECT_NAME} [...] mpich [...])
worked properly.
