Reicast won't start on Armbian64 #1902

Open pepitomaraja opened 4 years ago

pepitomaraja commented 4 years ago

Hi guys, my system is a tv box with s905x cpu and 2 gb ram. I've installed armbian64 bionic 5.7.0 and everything work fine. I've installed reicast latest version from source but when I launch ./reicast.elf it print the following error:

Personality: 00000000 Updated personality: 00000000 Linux paging: 4096 00001000 00000FFF

How I can fix it?

Peculiar error. Can you get us a backtrace w/ GDB?

As i understand, you are using a device with relatively limited capabilities, so you did not installed "git", and downloaded an archive file generated by the "Github" website directly via HTTP. ("Code", then "Download" buttons from the web interface.)

But you needed the "git" program while having downloaded the sources with it, because the build process retrieve the version string with the "git" program, and the "git" program retrieve it from the files generated while downloading trough it. These are missing requirements not mentioned in the "README.md" to the Linux building process.

I guess that when you start Reicast, the "substr" function call require at least one character, and Reicast can not find any version related acceptable string, so it return: __pos (which is 1) > this->size() (which is 0)

Size is 0. So it can't launch just because of one missing char related to the version string.

This thing can be located at STDOUT, at the very beginning of the "make" process under Linux... but everything could seem fine since the program can be compiled anyway.

As a workaround you can modify, properly, those lines from the "libswirl/core.mk" file:

$(VERSION_HEADER):
    echo "#define REICAST_VERSION \"`git describe --tags --always`\"" > $(VERSION_HEADER)
    echo "#define GIT_HASH \"`git rev-parse --short HEAD`\"" >> $(VERSION_HEADER)
    echo "#define BUILD_DATE \"`date '+%Y-%m-%d %H:%M:%S %Z'`\"" >> $(VERSION_HEADER)

to:

$(VERSION_HEADER):
    echo "#define REICAST_VERSION \"MyVersion\"" > $(VERSION_HEADER)
    echo "#define GIT_HASH \"aaaaaaaa\"" >> $(VERSION_HEADER)
    echo "#define BUILD_DATE \"`date '+%Y-%m-%d %H:%M:%S %Z'`\"" >> $(VERSION_HEADER)

I just modified the 2 lines from the middle.

I believe the leader of the project will agree to update this...

Thanks to him for every hours i spent on "De La Jet Set Radio"! But i don't like the WEBUI for security reasons and minimalism principles.
