Why does linking shared library require -lc on link line? also, I should mention that same openssl package compiles fine on solaris 10 with gcc using /usr/ccs/ tools instead of binutils. original gcc 3.4.3 on the install was built with /usr/ccs/bin/ld. 3998 niki.waibel 2005-07-05 14:39:30 +0000 okay. if -lc and -ldl is removed from the openssl makefile then openssl compiles fine. 4021 funtoos 2005-07-09 01:00:48 +0000 please also see bug 1021 4057 ebotcazou 2005-07-12 19:50:28 +0000 I can reproduce with GCC 4.0.1 and Binutils 2.16.1. 4058 ebotcazou 2005-07-12 20:09:05 +0000 Output of nm on /usr/lib/libdl.so.1: Solaris 10: [Index] Value Size Type Bind Other Shndx Name [34] | 0| 0|FUNC |GLOB |0 |ABS |dlclose [32] | 0| 0|FUNC |GLOB |0 |ABS |dldump [27] | 0| 0|FUNC |GLOB |0 |ABS |dlerror [35] | 0| 0|FUNC |GLOB |0 |ABS |dlinfo [28] | 0| 0|FUNC |GLOB |0 |ABS |dlmopen [18] | 0| 0|FUNC |GLOB |0 |ABS |dlopen [20] | 0| 0|FUNC |GLOB |0 |ABS |dlsym Solaris 7, 8 and 9: [Index] Value Size Type Bind Other Shndx Name [40] | 1828| 8|FUNC |WEAK |0 |7 |dlclose [38] | 1860| 8|FUNC |WEAK |0 |7 |dldump [32] | 1836| 8|FUNC |WEAK |0 |7 |dlerror [41] | 1796| 8|FUNC |WEAK |0 |7 |dlinfo [33] | 1804| 8|FUNC |WEAK |0 |7 |dlmopen [23] | 1812| 8|FUNC |WEAK |0 |7 |dlopen [25] | 1820| 8|FUNC |WEAK |0 |7 |dlsym Output of nm on /usr/lib/libc.so.1: Solaris 10: [6053] | 0| 0|FUNC |GLOB |0 |ABS |dlclose [7698] | 0| 0|FUNC |GLOB |0 |ABS |dldump [8132] | 0| 0|FUNC |GLOB |0 |ABS |dlerror [7686] | 0| 0|FUNC |GLOB |0 |ABS |dlinfo [6797] | 0| 0|FUNC |GLOB |0 |ABS |dlmopen [6142] | 0| 0|FUNC |GLOB |0 |ABS |dlopen [8293] | 0| 0|FUNC |GLOB |0 |ABS |dlsym Solaris 7, 8 and 9: [empty] Output of "man dlopen": Solaris 10: NAME dlopen, dlmopen - gain access to an executable object file SYNOPSIS #include <dlfcn.h> #include <link.h> void * dlopen(const char *pathname, int mode);
