[Linux] Building meshlab fails (nexus and libE57Format errors when compiling)

[Nalonoid]

Hello,

I am currently trying to build meshlab from the main branch, but compiling throws errors.

My system information:

kubuntu 23.10 x86_64
kernel 6.5.0-13-generic
qt 5.15.10
qt creator 10.0.2
gcc 13.2.0
cmake 3.27.4

external/downloads/libE57Format-2.3.0/include/E57Format.h
external/downloads/nexus-master/src/corto/src/tunstall.cpp

It is mainly undefined types such as:

‘int16_t’ has not been declared in ‘std’
‘uint32_t’ does not name a type
‘uint32_t’ has not been declared
Unknown type name 'uint32_t'

And so on...

What I did:

git clone --recursive https://github.com/cnr-isti-vclab/meshlab
mkdir meshlab/build && cd meshlab/build
cmake ..
make -j$(nproc)

Fails with the same errors as when opening meshlab with qtcreator.
Same result when using the scripts to build meshlab (0_setup_env.sh then 1_build.sh)
By the way, in the script 0_setup_env.sh the package qt5-default has no candidate for ubuntu based distros > 22.04. It should be replaced with qtbase5-dev and qt5-qmake.

Am I the only one with this build problem? :-(

Cheers

I don't experience these kind of errors... The only difference between your configuration and mine is the GCC version, therefore I think that some additional #include is required in that version. Maybe updating the external libraries should fix this issue, but it is something that I'll work on when Ubuntu 24.04 will be released.

I think I have the same problem as @Nalonoid. I get a bunch of "error: ‘uint32_t’ has not been declared in ‘std’" kind of errors in libE57Format-2.3.0/include header files.

My system information:
ubuntu 20.04 x86_64
qt 5.15.3
qt creator 6.0.2
gcc 10.5.0
cmake 3.29.0-rc1

I experience quite a few internal compiler errors and segmentation faults while running the make command as well.
