Hi, I test 1.7.90 on serveral Linux distributions using CFLAGS="-O3 -Wall" and "make" & "make check" shows no errors. But i got some warnings: 1. On gcc-4 systems (FC4+5, SUSE 10.0, Mandriva 2006) : $ make ... coulomb.c: In function 'gsl_sf_coulomb_wave_FG_e': coulomb.c:994: warning: 'G_lam_G' is used uninitialized in this function coulomb.c:996: warning: 'Gp_lam_G' is used uninitialized in this function ... fermi_dirac.c: In function 'fd_neg': fermi_dirac.c:946: warning: 's' may be used uninitialized in this function ... $ make check ... make[2]: Entering directory `/sw/gsl-1.7.90/diff' gcc -DHAVE_CONFIG_H -I. -I. -I.. -I.. -O3 -Wall -c test.c test.c: In function 'main': test.c:137: warning: 'DF1.params' is used uninitialized in this function test.c:137: warning: 'DF2.params' is used uninitialized in this function test.c:137: warning: 'DF3.params' is used uninitialized in this function test.c:137: warning: 'DF4.params' is used uninitialized in this function test.c:137: warning: 'DF5.params' is used uninitialized in this function test.c:137: warning: 'DF6.params' is used uninitialized in this function ... 2. during "configure" on SUSE 10.0 and SLES 9 i get : ... checking whether the gcc linker (/usr/i586-suse-linux/bin/ld) supports shared libraries... yes checking whether -lc should be explicitly linked in... no checking dynamic linker characteristics... cat: /etc/ld.so.conf.d/*.conf: No such file or directory GNU/Linux ld.so ...
