Difficulty Compiling MechVM for Ubuntu 10.04

[IronChefBoyardee]

I followed the instructions for compiling, and after I entered

Code: Select all

make

This came up

Code: Select all

g++ -c -pipe -O2 -Wall -W -D_REENTRANT -DQT_NO_DEBUG -DQT_GUI_LIB -DQT_CORE_LIB -DQT_SHARED -I/usr/share/qt4/mkspecs/linux-g++ -I. -I/usr/include/qt4/QtCore -I/usr/include/qt4/QtGui -I/usr/include/qt4 -I/opt/gnome/include/gtk-1.2 -I/opt/gnome/include/glib-2.0 -I/opt/gnome/include/glib-1.2 -I/opt/gnome/lib/glib-2.0/include -I. -o BGBase.o BGBase.cpp

Since I'm fairly new to compiling (and Linux), I wasn't sure what it meant, but after this message I attempted to open ./mechvm and it failed

Code: Select all

n-laptop:~/Documents/MechVM-2010-06-15/src$ ./mechvm
bash: ./mechvm: No such file or directory

If I'm overlooking something obvious I'd appreciate some guidance. Thank you in advance.

You seem to be missing the headers for SDL, probably need to install a package called SDL-devel.

[IronChefBoyardee]

I will try that and post here with the results. Thank you very much.

Necropost, yes... But you would need the package "libsdl1.2-dev"...
So

Code: Select all

sudo apt-get install libsdl1.2-dev

in your terminal should do it...

But you still won't be able to compile fully with that... To the developers of MechVM... You might want to change the linker options in the makefile since the old GTK libraries are no longer supported by most Linux distros... Meaning that GTK 2 would have to be used... I successfully compiled it after changing the linker option for glut to "-lglut `pkg-config --cflags gtk+-2.0 --libs`"

Ironchef: To compile, after typing "make" and running that, copypasta the following into your terminal:

Code: Select all

g++ -Wl,-O1 -o ../mechvm Archive.o BGBase.o BGString.o BipedMech.o Color.o Config.o Database_MW2.o dialogs.o FileCache.o FramerateCounter.o GLButton.o GLComboBox.o GLContextMenu.o GLLabel.o GLLineEdit.o GLScrollbar.o GLSlider.o GLSplitter.o GLTableView.o GLWindowContainer.o GLWindow.o Heightfield.o intersections.o LZdecode.o Matrix.o MechVM.o MechLab.o MechShell.o MechSim.o MechWarriorInstallers.o MechWarriorIIPRJ.o MechWarrior3ZBD.o Mesh.o MeshPolygon.o Mesh2.o MWBase.o MW2MechImporter.o Point3D.o QuadMech.o RenderableObject.o Texture.o TextureCompiler.o Toolbar.o VehicleAI.o Vehicles.o XMLTree.o -L/usr/lib -lGLU -lglut `pkg-config --cflags gtk+-2.0 --libs` -lSDL -lQtGui -lQtCore -lpthread

Oh, and the executables that were packaged for DOSBox will have to be renamed, then the original location linked to a local install of DOSBox... If you don't have it:

Code: Select all

sudo apt-get install dosbox

Then navigate to the DOSBox folder in your MechVM path... And do the following:

Code: Select all

cd DOSBox*
mv ./DOSBox.exe ./DOSBox.exe2
ln -s /usr/bin/dosbox ./DOSBox.exe

Things are very shaky, but the Mechlab works well, the games have problems of their own.
