Then their phase is irrelevant, and Tzlaine should draw inspiration from photos of jovian planets, not from physical considerations.

Nope. Under such pressure even hydrogen is solid.

Re: Segmentation Fault

Silvertree uses vertex buffer objects if it detects GL version >= 1.5 with GLEW. Otherwise it uses vertex arrays only.

Re: "GL/gl.h" header not found

If there's -lGiGi in command line and you get undefined references to GG:Clr::Clr() that means that it found libGiGi*.so but it couldn't find these symbols in these libraries.
What's the output of

Code: Select all

$ readelf --symbols /usr/local/lib/libGiGi.so | grep Clr
?

Re: "GL/gl.h" header not found

Do you have -lGiGi in linker command line? g++ -o freeoriond -pthread combat/Combat.o Empire/Empire.o Empire/EmpireManager.o Empire/ResourcePool.o network/Message.o network/MessageQueue.o network/Networking.o network/boost/error_code.o UI/StringTable.o universe/Building.o universe/Condition.o univer...

Re: "GL/gl.h" header not found

What's in linker command line that produces undefined references? Does it contain -lGiGi*? If it doesn't, try configuring GG with 'scons with_boost="/usr" configure' so env["LIBPATH"] exists. Make sure there are no python backtraces and it installs .pc files correctly.

Re: "GL/gl.h" header not found

This is, indeed, the cause. SCons script crashed when creating the .pc file and it won't add -l linker flags for GiGi if pkg-config fails.

Re: "GL/gl.h" header not found

Did you do "scons install" after compiling GG last time? Also, there could be old version with different suffix or in different directory that is used instead of the latest svn version...

Make sure that there's no old GiGi library somewhere in link path.

OpenGL Red Book is considered to be good material by OpenGL experts. Also, there are OpenGL man pages(E.g. try "man glNewList").

Re: Texture rotation

Assuming that OrthoBlit does actual rendering, if you rotate texture matrix before calling it and reset the matrix after calling it, then only these calls will be affected by rotation. If you want to restore previous texture matrix you can use glPushMatrix - glPopMatrix: glMatrixMode(GL_TEXTURE); gl...
