Hi My pet project for today was working on getting newmoon to build. I failed :/ I got the definition from ng0 and have improved a few things and updated it to the newest version. I investigated the 3 errors below: 1. sqlite3 needs to be compiled with SQLITE_ENABLE_FTS3 (this results in a lot of builds, patch attached) 2. our libvpx does not provide vpx_mem/vpx_mem.h even though it is in the source of libvpx it is not installed it seems. 3. the pulseaudio-error I do not understand: : fatal error: when writing output to : Broken pipe ?? Here are the errors with context: 0:19.11 checking for vpx >= 1.5.0... yes 0:19.11 checking MOZ_LIBVPX_CFLAGS... 0:19.11 checking MOZ_LIBVPX_LIBS... -L/gnu/store/7s6z2ybw86k7r97cwzrix9hngs729lrk-libvpx-1.8.0/lib -lvpx -lm 0:19.17 checking for vpx/vpx_decoder.h... yes 0:19.38 checking for vpx_codec_dec_init_ver in -lvpx... yes 0:19.42 checking for vpx_mem/vpx_mem.h... no 0:19.44 checking for libpulse... yes 0:19.45 checking MOZ_PULSEAUDIO_CFLAGS... -D_REENTRANT 0:19.45 checking MOZ_PULSEAUDIO_LIBS... -L/gnu/store/hd3x89yknm4k6k4gw16jy5xk7idq1sxf-pulseaudio-12.2/lib -lpulse 0:19.47 : fatal error: when writing output to : Broken pipe 0:19.47 compilation terminated. 0:19.48 /tmp/guix-build-newmoon-28.4.0.drv-0/source/old-configure: line 14935: test: : integer expression expected 0:19.50 checking for wget... no 0:19.52 checking for sqlite3 >= 3.26.0... yes 0:19.52 checking SQLITE_CFLAGS... 0:19.52 checking SQLITE_LIBS... -L/gnu/store/kg104rhqzvmnpqxk91ayvwxzsrncr0f4-sqlite-3.26.0/lib -lsqlite3 0:19.67 checking for SQLITE_SECURE_DELETE support in system SQLite... yes 0:19.78 checking for SQLITE_THREADSAFE support in system SQLite... yes 0:19.90 checking for SQLITE_ENABLE_FTS3 support in system SQLite... no 0:19.90 configure: error: System SQLite library is not compiled with SQLITE_ENABLE_FTS3. 0:19.93 DEBUG: 0:19.94 DEBUG: configure:15039: checking for wget 0:19.94 DEBUG: configure:15362: checking for sqlite3 >= 3.26.0 0:19.94 DEBUG: configure:15369: checking SQLITE_CFLAGS 0:19.94 DEBUG: configure:15374: checking SQLITE_LIBS 0:19.94 DEBUG: configure:15405: checking for SQLITE_SECURE_DELETE support in system SQLite 0:19.94 DEBUG: configure:15428: /gnu/store/n2p1zs14y89lwkg9da68y12pc10c6sw9-gcc-5.5.0/bin/gcc -std=gnu99 -o conftest -fno-strict-aliasing -fno-math-errno -msse2 -mfpmath=sse -pthread -lpthread -Wl,-z,noexecstack -Wl,-z,text -Wl,--build-id conftest.c -ldl -L/gnu/store/kg104rhqzvmnpqxk91ayvwxzsrncr0f4-sqlite-3.26.0/lib -lsqlite3 1>&5 0:19.94 DEBUG: configure:15451: checking for SQLITE_THREADSAFE support in system SQLite 0:19.94 DEBUG: configure:15474: /gnu/store/n2p1zs14y89lwkg9da68y12pc10c6sw9-gcc-5.5.0/bin/gcc -std=gnu99 -o conftest -fno-strict-aliasing -fno-math-errno -msse2 -mfpmath=sse -pthread -lpthread -Wl,-z,noexecstack -Wl,-z,text -Wl,--build-id conftest.c -ldl -L/gnu/store/kg104rhqzvmnpqxk91ayvwxzsrncr0f4-sqlite-3.26.0/lib -lsqlite3 1>&5 0:19.94 DEBUG: configure:15497: checking for SQLITE_ENABLE_FTS3 support in system SQLite 0:19.94 DEBUG: configure:15520: /gnu/store/n2p1zs14y89lwkg9da68y12pc10c6sw9-gcc-5.5.0/bin/gcc -std=gnu99 -o conftest -fno-strict-aliasing -fno-math-errno -msse2 -mfpmath=sse -pthread -lpthread -Wl,-z,noexecstack -Wl,-z,text -Wl,--build-id conftest.c -ldl -L/gnu/store/kg104rhqzvmnpqxk91ayvwxzsrncr0f4-sqlite-3.26.0/lib -lsqlite3 1>&5 0:19.94 DEBUG: configure: failed program was: 0:19.94 DEBUG: #line 15511 "configure" 0:19.94 DEBUG: #include "confdefs.h" 0:19.94 DEBUG: 0:19.94 DEBUG: #include "sqlite3.h" 0:19.94 DEBUG: 0:19.94 DEBUG: int main(int argc, char **argv){ 0:19.94 DEBUG: return !sqlite3_compileoption_used("SQLITE_ENABLE_FTS3"); 0:19.94 DEBUG: } 0:19.94 DEBUG: configure: error: System SQLite library is not compiled with SQLITE_ENABLE_FTS3. 0:19.94 ERROR: old-configure failed 0:19.98 *** Fix above errors and then restart with\ 0:19.98 "/gnu/store/7j3941iannrngdvgbclyxid12vds5w9i-make-4.2.1/bin/make -f client.mk build" 0:19.98 make[1]: *** [client.mk:378: configure] Error 1 make: *** [GNUmakefile:9: build] Error 2 -- Cheers Swedebugia
