I'm trying to compile Mono myself on Centos6.0. I downloaded the tarball mono-2.10.2.tar.bz2 on the official website. I followed the instructions. The configure command (./configure --prefix=/usr/local) worked good, but I get several undefined references during the linking of the /mono/profiler/mono-cov.c file. For instance I get an undefined reference to monoeg_malloc0.
Does someone know what's happening ?
Regards.
Use mono 2.10.8, it has been released a while ago.

I have problems building an executable file for a simple disease-transmission model implemented in C++, using cmake under macOS Monterey (v12.6.1). When I build the executable file, I obtain the following error when I try running it:
dyld[5281]: symbol not found in flat namespace (_cblas_caxpy) Abort trap: 6
The problem persists when I try to use XCode (v14.0.1) instead, resulting in the same error message.
Interestingly, my friend is able to build (& run) the executable file under macOS v10.15.7 without any problems.
Does anybody know what is going on here and how this issue can be resolved? The C++ project is publicly available on GitHub: https://github.com/AnnaMariaL/DengueSim
Any help would be very much appreciated.
Thanks!

tried: build an executable file with cmake, and Xcode under MacOS v12.16.1
expected: executable file
the program runs fine when launched under Xcode itself, but if I try to run the built executable from Xcode on the command line, that fails with the same error as for the CMake executable. So Xcode itself is, somehow, magically able to get this linker issue to resolve.
Your title/post is very confusing, however the issue isn't with cmake. It's with your cblas library and/or your linker. Look at the bug closely:
dyld[5281]: symbol not found in flat namespace (_cblas_caxpy) Abort trap: 6
Your linker is telling you that it can't find a function (symbol) in the given namespace. This is either due to the fact that your linker doesn't know where to find the correct library or you are linking against a wrong version of the library that doesn't have the symbols. The other issues might be related to how the library was built and with what it was built (architecture, compiler, etc...). This we can't answer because we don't have enough information to know for sure.
I'm trying to use rustlearn crate in my project. Added the dependency in Cargo.toml.
Since rustlearn requires gcc, I downloaded and installed MinGW64.
I tried the following gcc builds:
x86_64-8.1.0-posix-seh-rt_v6-rev0
x86_64-8.1.0-posix-sjlj-rt_v6-rev0
i686-8.1.0-posix-sjlj-rt_v6-rev0
each time setting a PATH environment variable to the appropriate g++.exe and restarting VSCode.
But everytime I tried to build my Rust package I got a such error:
= note: C:\Rust\PF\machinelearning\target\debug\deps\librustlearn-4ae611e3fd449ac0.rlib(svm.o): In function `ZN6KernelC2EiPKP8svm_nodeRK13svm_parameter':
C:\Git-local-repos\rustlearn/dependencies/libsvm/svm.cpp:256: undefined reference to `__gxx_personality_sj0'
C:\Git-local-repos\rustlearn/dependencies/libsvm/svm.cpp:256: undefined reference to `_Unwind_SjLj_Register'
C:\Git-local-repos\rustlearn/dependencies/libsvm/svm.cpp:258: undefined reference to `_Unwind_SjLj_Resume'
C:\Git-local-repos\rustlearn/dependencies/libsvm/svm.cpp:289: undefined reference to `_Unwind_SjLj_Unregister'
repeated many times.
I realize that the problem is somehow related to exception handling (seh/sjlj).
My system is Windows 7 x86-64, rust toolchain is stable-i686-pc-windows-gnu.
What am I doing wrong?
I found that the right build of MinGW is i686-7.1.0-posix-dwarf-rt_v5-rev2.
I did not run into these errors when I created a MWE.
To me, this looks like you are trying to use gcc to link a *.o that was compiled with g++.
I was unable to replicate your problem. Here's what I did--which resulted in a successfully built project:
I created a new project with cargo new and added the following to Cargo.toml:
rustlearn = "0.5.0"
I ran cargo check to download all the required dependencies.
I edited src/main.rs to include the logistic regression example from here, modified so that it was called in a main() function.
I ran cargo build, which successfully compiled crossbeam, libc, serde, rand, rustlearn, and rustlearn-test--the name of my test package. Several linting warnings were outputted; they were ignored.
I ran cargo run, which successfully ran the program.
FWIW, I'm using the WSL on Windows 10.
I'm trying to get a Python 3.4 interpreter into my app without to distribute python framework.
I'm linking with the libpython3.4.a (which appear to have dependency on Python.framework/versions/3.4/Python), but as guessed, it need python framework.
Does someone experienced this issue ?
Logically,i should be able to link statically (real static) and just distribute the python34.zip modules, right ?
Thanks for you help.
EDIT:
Finally i downloaded the Python 3.4 sources and build a static version.
Now i don't have dependency issue.
So i include the python3.4.zip near my executable.
But now, when starting the application i have this error:
"Fatal Python error: Py_Initialize: unable to load the file system codec"
So, i set Py_SetProgramName() to my binary and Py_SetPath(zippath) before the Py_Initialize().
But i still have the "ImportError: No module named 'encodings'" issue.
I also have tested with a simple folder instead of a zip.
I have searched everywhere online and no solutions work I'm getting soap_rand not defined along with a lot of other functions as well. Any ideas? I've tried using VS2013 C++ compiler and MingW32.
My latest attempt looked like this:
LDFLAGS+=" -L/c/openssl/ CXXFLAGS+=" -I/c/openssl/include/" configure
Then I try mingw32-make and get the error:
C:\Users\sfaber\AppData\Local\Temp\ccMoNxnb.o:httpda.c(.text+0x1a84): undefined reference to 'soap_rand'
I'm trying to compile the qtdensity example from the RInside examples folder, using Qt, Windows 7, R 32bit.
I have followed all the instructions posted online on how to set up these tools since my ultimate goal is to develop a C++/R application in Qt.
When I try to build the project I get the following error:
E:\dev\R-2.15.2\library\RInside\lib\i386\libRInside.a:-1: error: file not recognized: File truncated
Indeed, the libRInside.a file is empty as well as the libRInside.dll file in the same folder.
I have installed, uninstalled, installed again the RInside package using the install.packages("RInside", type="source") command.
The same problem does not occur with the Rcpp package, installed the same way.
I would greatly appreciate any insights on this. I've recently started with C++ and as a result it has taken me a lot of effort to set up everything so far.
Thank you!
Laura
Not sure what I did wrong but I solved it by copy-paste the same files from the archive available at the CRAN page of RInside
