[SOLVED] PCem v17 for Linux - compilation error with wx-main.cc:2:10

[DominoV]

Hello,

I am trying to compile PCem but I've run into some issues.

I have all dependencies installed and my machine is Ubuntu 22.04.1 LTS x86_64.

First of all, the command line doesn't recognize the "--enable-release" option, even though it is recommended in the README.md file. I get the following error:

"
configure: WARNING: unrecognized options: --enable-release
"

Simple "./configure" works and I continue with "make". The code starts compiling and after some time I get the following error:

"
wx-main.cc:2:10: fatal error: SDL2/SDL.h: No such file or directory
2 | #include <SDL2/SDL.h>
| ^~~~~~~~~~~~
compilation terminated.
make[1]: *** [Makefile:6217: pcem-wx-main.o] Error 1
make[1]: Leaving directory 'foo/PCemV17Linux/src'
make: *** [Makefile:365: all-recursive] Error 1
"

I have no idea how to fix this and why does this error occur. My knowledge about compiling is very basic. Please help.

Hi,

I am also new to pcem (discovered it today).

For "unrecognized options: --enable-release" message it seems there is only "-enable-release-build" now for Linux and BSD
For "SDL2/SDL.h" install "libsdl2-dev" (this is its name on Debian, and Ubuntu i guess) .

Hello,

Option "-enable-release-build" works. I installed "libsdl2-dev" as you recommended but I still get the following error:

"
wx-main.cc:2:10: fatal error: SDL2/SDL.h: No such file or directory
2 | #include <SDL2/SDL.h>
| ^~~~~~~~~~~~
compilation terminated.
make[1]: *** [Makefile:6217: pcem-wx-main.o] Error 1
make[1]: Leaving directory 'foo/PCemV17Linux/src'
make: *** [Makefile:365: all-recursive] Error 1
"

It seems like these libraries are not visible during compilation. Any idea how can I link them?

[thierrybo]

what is the output of:

dpkg -S SDL2/SDL.h

mine is

Code: Select all

dpkg -S SDL2/SDL.h
libsdl2-dev:amd64: /usr/include/SDL2/SDL.h

[DominoV]

My output is:

"
libsdl2-dev:amd64: /usr/include/SDL2/SDL.h
"

I actually re-installed all required libraries, including "libsdl2-dev", and it solved the issue. I was able to compile and run the program without error. It seems it could have been a problem with broken dependencies. So in the end installing "libsdl2-dev" is what fixed the issue.

Thank you for your help.
