Cannot compile with CLANG on Linux Mint [message #59655]

Hi,

For some reason I cannot compile with CLANG on Linux Mint anymore. GCC compilation still works, but CLANG halts on Core.h with:

/home/tom/upp.src/uppsrc/Core/Core.h:53:10: fatal error: 'typeinfo' file not found

This happened on both of my Linux installations quite recently.

Anyone else having similar issues? Any ideas how to solve this?

Best regards,

Tom

EDIT: OK, I manually added INCLUDE directories:
/usr/include/c++/11
/usr/include/x86_64-linux-gnu/c++/11

And LIB directories:
/usr/lib/x86_64-linux-gnu/11

Now I can compile, link and the executable runs.

What has changed so that I had to do this?

I guess if your compiler does not see <typeinfo> (which is internal header), it is not our fault - something must have gone wrong with your platform.

In any case, have tried without theide? Just create a file with #include <typeinfo> and try to compile it from command line (clang++ foo.cpp).

Mirek,

Sorry for the false alarm and thanks for the diagnostic tip. This is clearly not an U++ issue.

I followed your instructions and "clang++ foo.cpp" fails with the same error. So, CLANG compilation is broken on my both Linux Mint systems. It must be some unfortunate update that broke it, I guess.

Best regards,

Tom

Hi,

There's certainly something weird going on with Linux Mint. Again, building broke down, this time when linking. After digging a bit, I found that now the library location needed to be changed from what used to work.

In order to make it easier, I appended the current paths into .profile in my home directory:

export CPLUS_INCLUDE_PATH="/usr/include/c++/11:/usr/include/x86_64-linux-gnu/c++/11"
export LIBRARY_PATH="/usr/lib/gcc/x86_64-linux-gnu/11"

We'll see how long this works until it breaks again...

Best regards,

Tom

I just got an update on Ubuntu 20.04 and this just happened to me also.

The above environment changes also worked for me.

The current fix I found was to install libstd++-12-dev based off this post https://bugs.launchpad.net/ubuntu/+source/clang/+bug/1997600

Hi,

Thanks. Tried this and it works for me too. However, the package must be libstdc++-12-dev (not libstd++-12-dev):

sudo apt-get install libstdc++-12-dev

Best regards,

Tom
