VS-0.5.3 compile failure - Debian 9 64 bit

Trying to build your own version of Vega Strike and having problems? Unix users, paste your config.log here (stderr output alone is not helpful).

VS-0.5.3 compile failure - Debian 9 64 bit

Postby wirser » Thu Feb 20, 2020 11:36 pm

Aside for some warnings I got to compile vegastrike.
However the ending message was
[100%] Building CXX object CMakeFiles/vegastrike.dir/src/python/briefing_wrapper.cpp.o
[100%] Linking CXX executable vegastrike
[100%] Built target vegastrike
cp: cannot stat {edited_home_dir}/build/Vega-Strike-Engine-Source-0.5.3/build/{vegastrike,vegaserver,setup/vssetup,objconv/mesh_tool}': No such file or directory
enon@ws-0:~/build/Vega-Strike-Engine-Source-0.5.3$ bin/vegastrike
bash: bin/vegastrike: No such file or directory

:~/build/Vega-Strike-Engine-Source-0.5.3$ ls ./bin
:~/build/Vega-Strike-Engine-Source-0.5.3$



The built binaries were found in the "/Vega-Strike-Engine-Source-0.5.3/build" folder, however trying to run from {VS}/build/vegastrike produced this
$ build/vegastrike
Registering codec ogg.
In path /{edited_home_dir}/Vega-Strike-Engine-Source-0.5.3/build
Vega Strike
See http://www.gnu.org/copyleft/gpl.html for license details.

GOT SUBDIR ARG =
Found MODDIR = /mods
USING HOMEDIR : {edited_home_dir}.vegastrike As the home directory
CONFIGFILE - No config found in home :{edited_home_dir}/.vegastrike/vegastrike.config
CONFIGFILE - No config found in data dir : /vegastrike.config
CONFIG FILE NOT FOUND !!!
Panic exit - no configuration

so I tried running
$ build/setup/vssetup
and got
Error: Failed to find Version.txt anywhere.

looking further I found {VS}/data empty (not mentioned in README.md)
So I unzipped "Assets-Production-0.5.3.zip" and copied everthing from inside the "Assets-Production-0.5.3" folder into the {VS}/data foleder
BTW could you change the name from "Assets-Production-0.5.3" to data to avoid confusion.

Both " build/setup/vssetup" and "build/vegastrike" execute
"config.log" not found

In such a huge codebase, gcc sometimes gets confused with multi-threaded compilation. In such cases, cd build and make -j1 to see if the problem comes from that.

Help with codebase maintenance is always welcome ;-)

make completed correctly, I tracked the problem to the last line {VS_root}}/sh/vsbuild.sh
Code: Select all
cp $BUILD_DIR/{vegastrike,vegaserver,setup/vssetup,objconv/mesh_tool} $BIN_DIR

I toyed around a bit trying to solve the porblem ( before moving on to actually testing game :lol:

2 thoughts
Debian uses "Dash" instead "Bash" for normal shell scripts via /bin/sh. maybe this is specific to Dash.
And/or possibly some strange function on how cp behaves in a shell script. From what few examples I looked it looks fine. I tried using -R (recursive) option to no avail.

I even tried executing this line from direct cmdline. still nogo.

I'll kill some brain cells over the weekend on this :wink:

The safest way would be to split this line into one cp per file.

I was right about suspecting bash/dash difference. I had thought about splitting up like you said.
but if you change the " #!/bin/sh" ---> "#! /bin/bash" the script euns correctly

See
https://stackoverflow.com/questions/5725296/difference-between-sh-and-bash/5725402#5725402
for a better explination

"BUT I Got all these other sh files"
Code: Select all
 grep -rl '#!/bin/sh' ./ | xargs sed -i 's\#!/bin/sh\#!/bin/bash\g'

will change all sh files recursiely (i am using this trick to change cs_*.h related #includes to respective Python #includes)

Thank you for the info, I stumbled on this on Ubuntu too.

I think the better command would be:
Code: Select all
  grep --exclude-dir='.git/' -rl '#!/bin/sh' ./ | xargs sed -i 's\#!/bin/sh\#!/bin/bash\g'


Just so you won't change anything in the .git/ files :)

well changing /bin/sh to /bin/bash should run just fine - even .git/ files :roll:
it would be the same as if /bin/sh pointed to /bin/bash, as some do :shock:

It realy is a small point when the 0.5.3 GitHub branch gets stomped upon :cry:
