While compiling a program (gpx2video), the linker gives me various errors with libraries (incompatible, not found)

CMake Error at /usr/share/cmake-3.25/Modules/CMakeTestCCompiler.cmake:70 (message):
   The C compiler

     "/usr/bin/cc"

   is not able to compile a simple test program.

   It fails with the following output:

It looks like you have a non-compatible `ld` program in `/usr/local` (which is found first, due to `$PATH` order) - everything in the standard Ubuntu toolchain would be in `/usr`

So, what can I do? I had already reinstalled binutils

There's a bunch of things you can try - (1) defining your `PATH` such that `/usr/bin` precedes `/usr/local/bin` (2) using the available `CMAKE` variables to specify the correct linker e.g. you could try re-running `cmake` with `-DCMAKE_C_FLAGS="-fuse-ld=/usr/bin/ld"` or (3) removing the incompatible toolchain (if it serves no purpose). See for example [CMake: use a custom linker](https://stackoverflow.com/questions/1867745/cmake-use-a-custom-linker).

Tried both of your suggested solutions to no avail. The error is always there.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
