Hi, I am having the same make error that Richard Hornby reported in October. I am running Cygwin on XP, not Linux. I am a graduate student who would like to download the FlightGear source code with the hopes of extending it to test aircraft control algorithms I have been designing.
I followed the installation instructions to the letter; I even cleared out Cygwin and reinstalled it with all of the recomended options. I was able to build ZLIB, Metakit, PLIB, and Simgear, and the configure script for FlightGear seems to pass, with this message: Configure Summary ================= Prefix: /usr/local Plib PSL scripting: You will not be able to run scripts written in PSL and some advanced GUI and input features may not work. Download and install the latest CVS version of plib if you would like to enable PSL support. Debug messages: yes Automake version: automake (GNU automake) 1.7.6 Using FGEnvironment Using default multiplayer support threads: no When I run make, I get this (which ends with an error): Making all in tests make[1]: Entering directory `/usr/local/source/FlightGear-0.9.3/tests' source='est-epsilon.c' object='est-epsilon.o' libtool=no \ depfile='.deps/est-epsilon.Po' tmpdepfile='.deps/est-epsilon.TPo' \ depmode=gcc3 /bin/bash ../depcomp \ gcc -DHAVE_CONFIG_H -I. -I. -I../src/Include -g -O2 -c `test -f est-epsilon. c || echo './'`est-epsilon.c gcc -g -O2 -L/usr/X11R6/lib -o est-epsilon.exe est-epsilon.o source='gl-info.c' object='gl-info.o' libtool=no \ depfile='.deps/gl-info.Po' tmpdepfile='.deps/gl-info.TPo' \ depmode=gcc3 /bin/bash ../depcomp \ gcc -DHAVE_CONFIG_H -I. -I. -I../src/Include -g -O2 -c `test -f gl-info.c || echo './'`gl-info.c gcc -g -O2 -L/usr/X11R6/lib -o gl-info.exe gl-info.o -lglut32 -lglu32 -lopeng l32 -luser32 -lgdi32 source='test-gethostname.cxx' object='test-gethostname.o' libtool=no \ depfile='.deps/test-gethostname.Po' tmpdepfile='.deps/test-gethostname.TPo' \ depmode=gcc3 /bin/bash ../depcomp \ g++ -DHAVE_CONFIG_H -I. -I. -I../src/Include -g -O2 -c -o test-gethostname.o `test -f test-gethostname.cxx || echo './'`test-gethostname.cxx g++ -g -O2 -L/usr/X11R6/lib -o test-gethostname.exe test-gethostname.o source='test-mktime.cxx' object='test-mktime.o' libtool=no \ depfile='.deps/test-mktime.Po' tmpdepfile='.deps/test-mktime.TPo' \ depmode=gcc3 /bin/bash ../depcomp \ g++ -DHAVE_CONFIG_H -I. -I. -I../src/Include -g -O2 -c -o test-mktime.o `tes t -f test-mktime.cxx || echo './'`test-mktime.cxx g++ -g -O2 -L/usr/X11R6/lib -o test-mktime.exe test-mktime.o source='test-text.cxx' object='test-text.o' libtool=no \ depfile='.deps/test-text.Po' tmpdepfile='.deps/test-text.TPo' \ depmode=gcc3 /bin/bash ../depcomp \ g++ -DHAVE_CONFIG_H -I. -I. -I../src/Include -g -O2 -c -o test-text.o `test -f test-text.cxx || echo './'`test-text.cxx g++ -g -O2 -L/usr/X11R6/lib -o test-text.exe test-text.o source='test-up.cxx' object='test-up.o' libtool=no \ depfile='.deps/test-up.Po' tmpdepfile='.deps/test-up.TPo' \ depmode=gcc3 /bin/bash ../depcomp \ g++ -DHAVE_CONFIG_H -I. -I. -I../src/Include -g -O2 -c -o test-up.o `test -f test-up.cxx || echo './'`test-up.cxx g++ -g -O2 -L/usr/X11R6/lib -o test-up.exe test-up.o -lsgmath -lsgdebug -lpli bsg -lplibul /usr/lib/gcc-lib/i686-pc-cygwin/3.3.1/../../../../i686-pc-cygwin/bin/ld: cannot find -lsgmath collect2: ld returned 1 exit status make[1]: *** [test-up.exe] Error 1 make[1]: Leaving directory `/usr/local/source/FlightGear-0.9.3/tests' make: *** [all-recursive] Error 1 If anyone knows how I can fix this, I would appreciate it.
