Steps to reproduce

cmake configure
and then
make
waith and jjust at linkign got the error

[mckaygerhard]

after some investigations seems the libcurl.a must be linking using target_link_libraries from cmake.. but i dont know how! seems same problem as #8482 but strange due does not always got this error, only when compiling 5.0.X ..

when i try 0.4.X got only the error of issue #8482

please can provide me directions to solve it?

[mckaygerhard]

revised and seem i hav proper curl detection:

-- Using LuaJIT provided by system.
-- Found CURL: /usr/lib/libcurl.a  
-- cURL support enabled.
-- Found GetText: /usr/include  

but not seems cmake use the curl-config output linking libs for static.. i got proper version:

 curl-config  --static-libs
/usr/lib/libcurl.a -lidn -lrtmp -lgcrypt -lgnutls -lgssapi_krb5 -lkrb5 -lk5crypto -lcom_err -llber -lldap -lz -lrt
curl --version
curl 7.35.0 (i486-pc-linux-gnu) libcurl/7.35.0 OpenSSL/0.9.8o zlib/1.2.3.4 libidn/1.15 librtmp/2.3

[SmallJoker]

So you're using GCC 4.4.5? Try again after updating it to version 4.9 (or higher), which is also stated as a requirement in the README.

[mckaygerhard]

hey-- the curl linking proble its due the cmake trange rules..

after added proper linkg all problems gone:

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()

please give a break with micosoft like "update to lasted" responses!!!

[mckaygerhard]

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

and please stop to say "update to lasted" i not using windo! gcc doe snot have nothig related here, i'll explain to you @SmallJoker >

1. seems some of the libraryes used in mostly distros embebed the linking option and when user need a specific static link does not have it if not used right linker..
2. and about gcc 4.4 : i compiled with duegive more optimization level with less memory rather thant gcc 7 that consumes too much ram with luajit (do you read the luajit readme for compilation???)
3. gcc 3.X does more level of optimization.. with less ram! but i cannot make compiled yet!
