The attached one-line patch fixes the problem. My software [1] uses autoconf and incorporates the macro file libtool.m4 into the configure script. On Solaris 11.3 I get the following in config.log: libltdl_cv_preloaded_symbols=3Dno This is a change from Solaris 11.2 when the result was "yes". The bug strikes when the variable "lt_cv_sys_global_symbol_pipe" is set. The built-in test for the global symbol pipe fails and it is reset to null. The program conftest.c created for the test of the global symbol pipe is: #ifdef __cplusplus extern "C" { #endif char nm_test_var; void nm_test_func(void); void nm_test_func(void){} #ifdef __cplusplus } #endif int main(){nm_test_var=3D'a';nm_test_func();return(0);} Under Solaris 11.2, the result of "/usr/bin/nm -p" on the object file for this test program is 0000000032 T main 0000000016 T nm_test_func 0000000001 D nm_test_var (additional lines of output omitted for clarity). Under 11.3 this is now 0000000032 T main 0000000016 T nm_test_func 0000000001 C nm_test_var So nm_test_var is now listed as common ("C") instead of initialized data ("D"). This brings the behaviour of Oracle's nm in line with the GNU version.=20 Currently "C" is not recognized as a possible symbol code on Solaris. Therefore nm_test_var is not extracted by the global symbol pipe and the test fails. This bug is fixed in the attached patch for libtool.m4, which adds "C" to the regular expression symcode for Solaris. best regards Martyn Plummer PS The nm utility on Solaris is provided by the base-developer-utilities package, and the change occurred between versions 0.5.11-0.175.2.0.0.42.2 and 0.5.11-0.175.3.0.0.30.0.
