I'm trying to build Git and install it in a discardable directory. All of Git's prereqs have been built and are there. Git was configured with --with-curl, but it looks like Git cannot find the cURL built for it (see below). I tried adding -lcurl to LDLIBS but it does not appear to be honored. cURL is also available from PKG_CONFIG_PATH, but it does not appear it is being used: $ PKG_CONFIG_PATH=/var/sanitize/lib64/pkgconfig pkg-config --print-provides libcurl libcurl = 7.64.0 My question is, how can I get the behavior of --with-curl-path=<custom path>? At the moment the only option offered is --with-curl. $ make V=1 ... make: curl-config: Command not found ... gcc -I/var/sanitize/include -DNDEBUG -g2 -O2 -fsanitize=undefined -march=native -fPIC -I. -DHAVE_SYSINFO -DGIT_HOST_CPU="\"x86_64\"" -DUSE_LIBPCRE2 -I/var/sanitize/include -DHAVE_ALLOCA_H -I/var/sanitize/include -I/var/sanitize/include -I/var/sanitize/include -I/var/sanitize/include -DSHA1_DC -DSHA1DC_NO_STANDARD_INCLUDES -DSHA1DC_INIT_SAFE_HASH_DEFAULT=0 -DSHA1DC_CUSTOM_INCLUDE_SHA1_C="\"cache.h\"" -DSHA1DC_CUSTOM_INCLUDE_UBC_CHECK_C="\"git-compat-util.h\"" -DSHA256_BLK -DHAVE_PATHS_H -DHAVE_LIBCHARSET_H -DHAVE_STRINGS_H -DHAVE_DEV_TTY -DHAVE_CLOCK_GETTIME -DHAVE_CLOCK_MONOTONIC -DHAVE_GETDELIM '-DPROCFS_EXECUTABLE_PATH="/proc/self/exe"' -DFREAD_READS_DIRECTORIES -DNO_STRLCPY -DSHELL_PATH='"/bin/sh"' -DPAGER_ENV='"LESS=FRX LV=-c"' -o git-http-fetch -L/var/sanitize/lib64 -fsanitize=undefined -Wl,-R,/var/sanitize/lib64 -Wl,--enable-new-dtags http.o http-walker.o http-fetch.o common-main.o \ -L/var/sanitize/lib64 -Wl,-rpath,/var/sanitize/lib64 libgit.a xdiff/lib.a -lpcre2-8 -L/var/sanitize/lib64 -Wl,-rpath,/var/sanitize/lib64 -L/var/sanitize/lib64 -Wl,-rpath,/var/sanitize/lib64 -lz -L/var/sanitize/lib64 -Wl,-rpath,/var/sanitize/lib64 -liconv -lcharset -lrt -lpthread /bin/ld: http.o: in function `http_opt_request_remainder': /home/test/git-2.21.0/http.c:1833: undefined reference to `curl_easy_setopt' /bin/ld: http.o: in function `process_curl_messages': /home/test/git-2.21.0/http.c:261: undefined reference to `curl_multi_info_read' ...
