But I invoked the gdb using the following command in $(curl-src)/tests/: ``` ~/curl/tests$ ./runtests.pl 546 -g ``` I haven't found a greate way to run the command in glibc directory, as it seems `runtests.pl` found the curl binary using relative path :/. Are there some methods like adding a environment variable so gdb will search in the glibc source code. And I was quite surprised that gdb in different distributions can have different behavior :-). Best, Zhaoming
