compiling c++ from linux to windows using g++ and got an error.
Error:
undefined reference to `FOLDERID_RoamingTiles'
collect2: error: ld returned 1 exit status
I'm guessing there is a library I have to reference but I don't know what the name is.
also if that's the case what are the ways I could find the name of the library I have to reference, if that happens again in the future?
thanks.
I'm compiling under msys2/gcc. linking to uuid helped me.
g++ -luuid -o ....

I am fairly new to Fortran and this may sound like a silly question. I encounter an error when compiling the Fortran code that is posted as an example in the NLOPT Wiki.
I compile in Ubuntu 18.04 LTS using the following command:
gfortran example-nlopt.f90 -o example-nlopt -I/usr/local/include/
The following error is produced in the terminal:
/tmp/ccbAim6b.o: In function `MAIN__':

Based on what I saw in nlopt's documentation (https://nlopt.readthedocs.io/en/latest/NLopt_Installation/#changing-the-installation-directory) it looks like you just need to specify the library to link against. Maybe try this:
gfortran -I/usr/local/include/ -L/usr/local/lib example-nlopt.f90 -o example-nlopt -lnlopt -lm
This assumes you have the libnlopt.so in /usr/local/lib, if not then point to its location with the -L option.
I am trying to compile the Jasmine OpenSSD code with arm-none-eabi-g++.
However, it first failed with the following error message
/usr/lib/gcc/arm-none-eabi/4.8.2/../../../arm-none-eabi/bin/ld: cannot find -lstdc++
To fix that, I ensured that linking with libstdc++.a was possible. Once I fixed that, it failed with the following errors:

Here is the actual step at which it fails:
arm-none-eabi-g++ -static -nostartfiles -ffreestanding -T ld_script -Wl,-O1,-Map=list.txt ftl.o sata_identify.o sata_cmd.o sata_isr.o sata_main.o sata_table.o initialize.o mem_util.o flash.o flash_wrapper.o misc.o uart.o init.o -o firmware.elf -L"/usr/lib/gcc/arm-none-eabi/4.8.2/" -lgcc
Can someone suggest a fix? Also, this works perfectly well if I use arm-none-eabi-gcc instead of arm-none-eabi-g++
Your problem is caused by exception handling code that is produced by the compiler, which relies on runtime components - those are not present in your build.
-fno-exceptions turns off exception handling in the code-generation of the compiler.

I sucessfully ran small demos of Qt4.8.6 alone and one with Qwt.
The only doubt I have is regarding the ftd2xx lib.
But, I think it is linked properly because I am able to produce errors of undefined function if I don't link the DLL.
The error message is not clear to me. So, I have absolutely no idea where to look from here!
Could someone help me?
Thank you!
I have a simple socket program that I'm trying to compile using g++ running in mingw (both the latest versions) on a Win8 system. I'm getting the common linker errors
undefined reference to `__imp_socket'
undefined reference to `__imp_gethostbyname'
I've tried adding -lws2_32 with no luck; i.e. it still can't find the references. Can someone suggest something else I might be missing?
Here's the full output:

Try putting the -lws2_32 after the test_client.C parameter. The linker of gcc (ld) is touchy about the order of linkable things, this is probably why it doesn't find your imported functions at link time.
I am new to posix thread library, and I tried to compile a sample code from a tutorial with:
g++ -lpthread agreement.cpp -o agreement
however I was not able to compile the code and got the following error message:

I am aware that -lpthread is needed for compilation to work, but is there any other options i might need to solve the problem? if not how do I have to install the "proper" pthread library?
Thanks for your help!
You want the compile option -pthread (if you are really using pthreads). If you just need those functions they are in librt so use -lrt
