after some investigations seems the libcurl.a must be linking using target_link_libraries from cmake.. but i dont know how!

please can provide me directions to solve it?

[mckaygerhard]

after some investigations got the problem: its due minetest cmake does not property use the curl's curl-config utility and does not property linking.. the linking relly on other program.. this makes causing problems in chrooted and minimalistig environments for static builds

CMakeLists.txt
@@ -770,6 +770,8 @@ else()
 	if(MINGW)
 		set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} -mwindows")
 	endif()
+
+	SET( CMAKE_EXE_LINKER_FLAGS  "${CMAKE_EXE_LINKER_FLAGS} -lidn -lrtmp -lcom_err -llber -lz -lrt" )
 endif()

i do not jhave exact link flags but i suspect with -lrtmp are enought. but real problem its the not right usage of the curl config utility that provides right linker

and please stop to say "update to lasted" i not using windo!
