Failed to compile uncertainty_pnp on ubuntu 20.04 using compile_all.sh

[GiantRabbit12138]

Hi, could you please help me with the following issue? @wangg12 @goodfella47 @Rainbowend @lolrudy @tzsombor95
When I compile using the compile_all.sh script, uncertainty_pnp failed to compile successfully. I'm using Ubuntu version 20.04. The error screenshot is as follows:

@GiantRabbit12138 Maybe your gcc version is not compatible with this code. Try to use 5.4.0 gcc version.

@tzsombor95 Thank you for your reply! According to your suggestion, I replaced the original gcc 9.4.0 with gcc 5.4.0. However, the previous error in compiling uncertainty_pnp did not disappear. In addition, packages such as flow and ransac_voting also prompt that the gcc version is too low. In fact, the two errors reported by gcc before only appeared when compiling uncertainty_pnp (i.e. gcc: error: ./lib/libceres.so: No such file or directory and gcc: error: ./lib/libglog.so: No such file or directory) Could you please give me some other suggestions? By the way, my operating system is ubuntu22.04, python version is 3.8, cuda version is 11.6, and pytorch version is 1.13.1.

@GiantRabbit12138 I checked my environment, I have 9.4.0 gcc, so it was a good start. Did you run scripts/install_deps.sh before compile_all.sh script?

@tzsombor95 Yes, in order to avoid ignoring some wrong installation information, I executed the installation command line by line(install_depth.sh). However, uncertainty_pnp still failed to compile successfully. Then I started to look at the error content of gcc. It showed that it would use two dynamic library files in the ./lib folder during compilation, but I did not find these two files in the ./lib folder. So I would like to ask how to generate these two files.

However, if this was a common problem, I might have found it in the issue, but I didn't find the same problem as mine in the issue, which makes me wonder if there is another reason causing this problem.

@tzsombor95 Thank you, sir. Following the steps in INSTALL.md, I successfully generated the libceres.so file. As for libglog.so, I used the whereis command to find its directory and created a symbolic link using the sudo ln -s command. Finally, I created a lib directory under the uncertainty_pnp directory and placed these two files in it. The compilation did not report any errors in the end.
The compilation result of the uncertainty_pnp library is:
