Error when trying to compile arm64 Linux

[kero990]

I tried to compile this project on a Linux machine with arm64 architecture, but I got the following error.

I am not sure whether the missing key file is necessary, nor do I confirm the practical significance of the second error. But it obviously does not generate a makefile. What is the problem? Is it related to architecture?

Hi,

It doesn't seems related to an architecture problem but more to a platform one. Did you init git submodules ? Else, could you try with the "dev" branch ?

[kero990]

Accessing github is a bit difficult in my area, so I use mirror sites when I'm in git. However, mirror sites can't handle submodules, so I git cloned libcross2d and sscrap separately, I'm not sure what's the difference between this and a direct git clone --recursive full project, or how do these two subprojects need to be initialized?

@Cpasjuste
Hi, it was true that my submodule was incomplete last time. This time I completely cloned the entire project, but stopped at 10% when making, evertime. I even compiled on a fully reset debian10 with a virtual machine and the result was the same. I haven't tried higher debian versions yet, but I suspect that binaries compiled with higher versions also won't work on debian10. Is this a debian issue, maybe I should try Ubuntu?

In addition, I have found some errors in the cmake log

like this,too many
So is this a debian issue or a version too low issue?

I have tried many times, including on debian and ubuntu on the x64 platform, and now I will get stuck on compiling the cross2d subproject. Whether it is compiling the entire pemu or trying to compile cross2d alone, there is no success. The current error is as follows.

Hi, is this still a problem with latest version ?

Hi, is this still a problem with latest version ?

There are no issues with the compilation now, the problem lies at runtime. I can run it perfectly on the latest Ubuntu latest, but since my arm device only has debian10, there may be some issues running on debian10, and currently it will report an error:

umount: /tmp/c2d_ Romfs: Insufficient permissions
fuse: bad mount point `/tmp/c2d_ romfs/': Permission denied
POSIXRomFs::POSIXRomFs: fuse_ setup failed

If I use sudo to run, there will be no errors, but no interface will appear, and you cannot use Ctrl+C to terminate the run. can only kill the process.

Hi, i removed the "hacky" fusefs romfs on linux and now just copy the romfs files to "data_romfs" insead release folder, this may fix your problem.
