Hello, on the analysis homepage you explain how to install the distribution packages to link analysis against. The installCode.py locates the files in fedora and compiles. On this list there are already some posts about additional subdirs on debian or ubuntu. Setting these paths manually in the environment.txt works if the dev packages are present and analysis will compile. CC = cc MALLOC_FLAG = FPIC_FLAG = -fPIC XOR_FLAG = CFLAGS = -O $(MALLOC_FLAG) $(FPIC_FLAG) $(XOR_FLAG) IGNORE_GL_FLAG = GL_FLAG = -DUSE_GL_FALSE GLUT_NEED_INIT = -DNEED_GLUT_INIT GLUT_NOT_IN_GL = GLUT_FLAG = $(GLUT_NEED_INIT) $(GLUT_NOT_IN_GL) SHARED_FLAGS = -shared MATH_LIB = -lm X11_DIR = /usr X11_LIB = -lX11 -lXext X11_INCLUDE_FLAGS = -I$(X11_DIR)/include X11_LIB_FLAGS = -L$(X11_DIR)/lib TCL_DIR = /usr TCL_LIB = -ltcl8.4 TCL_INCLUDE_FLAGS = -I$(TCL_DIR)/include/tcl8.4 TCL_LIB_FLAGS = -L$(TCL_DIR)/lib/tcl8.4 TK_DIR = /usr TK_LIB = -ltk8.4 TK_INCLUDE_FLAGS = -I$(TK_DIR)/include/tcl8.4 TK_LIB_FLAGS = -L$(TK_DIR)/lib/tcl8.4 PYTHON_DIR = /usr PYTHON_LIB = PYTHON_INCLUDE_FLAGS = -I$(PYTHON_DIR)/include/python2.5 PYTHON_LIB_FLAGS = -L$(PYTHON_DIR)/lib/python2.5 GL_DIR = /usr GL_LIB = -lglut -lGLU -lGL GL_INCLUDE_FLAGS = -I$(GL_DIR)/include/GL GL_LIB_FLAGS = -L$(GL_DIR)/lib But the software does not function correctly if linked against the system libraries! For example the formatConverter just hangs without further output while reading files. I tried Sparky proj files, save files and Cyana upl files. This happens on fc6, fc8 and ubuntu 7.10, all x64. After compiling the python tcl/tk tarballs from your homepage and linking analysis against them the file import works. (On an old opensuse 10 x86 it worked with the system libraries too.) If this is hopefully easy to resolve the following completes the instructions on the download page for ubuntu 7.10: aptitude install tcl8.4-dev tk8.4-dev python-dev freeglut3-dev python-tk build-essential X11 and GL headers sould already be present after installing the latest drivers via the envy script: http://www.albertomilone.com/nvidia_scripts1.html Tolga
