Hi Mike, I don't know why I didn't think of trying to clone the git repo before consulting the mailing list. However, I have choosen to create a patch for pcap_capture.c and process_packet.c, as my build system use tarballs. After applying the patch fwknop compiles fine, but an error occurs while linking: ... libtool: link: arm-linux-musleabihf-gcc -g -O2 -Wall -Wformat -Wformat-security -fstack-protector-all -fstack-protector -fPIE -D_FORTIFY_SOURCE=2 -Wall -Wformat -Wformat-security -fstack-protector-all -fstack-protector -fPIE -pie -D_FORTIFY_SOURCE=2 -Wl,-z -Wl,relro -Wl,-z -Wl,now -o .libs/fwknopd fwknopd-fwknopd.o fwknopd-config_init.o fwknopd-incoming_spa.o fwknopd-pcap_capture.o fwknopd-process_packet.o fwknopd-log_msg.o fwknopd-utils.o fwknopd-sig_handler.o fwknopd-replay_cache.o fwknopd-access.o fwknopd-fwknopd_errors.o fwknopd-tcp_server.o fwknopd-udp_server.o fwknopd-fw_util.o fwknopd-fw_util_ipf.o fwknopd-fw_util_firewalld.o fwknopd-fw_util_iptables.o fwknopd-fw_util_ipfw.o fwknopd-fw_util_pf.o fwknopd-extcmd.o ../lib/.libs/libfko.so ../common/libfko_util.a -Wl,-rpath -Wl,/home/aic0azee/fwknop/lib ../lib/.libs/libfko.so: undefined reference to `rpl_realloc' collect2: error: ld returned 1 exit status make[2]: *** [fwknopd] Error 1 make[2]: Leaving directory `/home/aic0azee/fwknop-2.6.5/server' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/aic0azee/fwknop-2.6.5' make: *** [all] Error 2 I have been told the error is related to how the autoconf tool checks if the libc supports malloc features. A workaround is to export the variable "ac_cv_func_realloc_0_nonnull=yes": aic0azee@localhost:~$ ac_cv_func_realloc_0_nonnull=yes ./configure --host=arm-linux-musleabihf --prefix=/home/aic0azee/fwknop --enable-udp-server --disable-client --with-iptables=/sbin/iptables I can confirm that fwknop builds cleanly after exporting the variable. Is it fine to use fwknop with the workaround described, or is it possible that adverse effects could arise? ------------------------------------------------------------------------------ Dive into the World of Parallel Programming The Go Parallel Website, sponsored by Intel and developed in partnership with Slashdot Media, is your hub for all things parallel software development, from weekly thought leadership blogs to news, videos, case studies, tutorials and more.
