0.79.0.1/2 unitsync: undefined symbol

[SirMaverick]

I compiled the sources for 0.79.0.1 and 0.79.0.2. When I tried to start SpringLobby, I get an error when it tries to load unitsync.so:"undefined symbol: _ZN8Platform13GetBinaryPathEv"

This does not happen with 0.78.2.1 and 0.79.0. They work fine.

$ grep -r ZN8Platform13GetBinaryPathEv .
Binary file ./build/spring matches
Binary file ./build/rts/System/ConfigHandler.o matches
Binary file ./build/rts/System/FileSystem/DataDirLocater.o matches

Binary file ./build/rts/System/Platform/Misc.o matches
Binary file ./build/unitsync/rts/System/ConfigHandler.cpp.os matches
Binary file ./build/unitsync/unitsync.so matches

setup:
no special configuration to compile the source (no extra parameter to scons)
gcc version 4.3.3

try building with cmake instead?

[imbaczek]

strange :/

try scons -c and then rebuild.

The rts/System/Platform/Misc.cpp source file is missing from .79.0.*'s SConstruct. Patch to fix it:

Code: Select all

git diff SConstruct
diff --git a/SConstruct b/SConstruct

Seems http://github.com/spring/spring/commit/ ... 9e3d96ff04 didn't make it into the .79 release branch.

Worked.
(libunitsync.so (cmake) is 2 times bigger than unitsync.so (scons))

try scons -c and then rebuild.

I build on fresh sources. That did not help.

That fixed unitsync built with scons.
