curl compile faild with ssh2

[kingbrant]

When i compile with ssh2, i configured it --with-zlib=$(STAGING_DIR)/usr/ --with-ssl=$(STAGING_DIR)/usr/ --with-libssh2=$(PKG_INSTALL_DIR)/usr --enable-shared --enable-static ac_cv_func_SSLv2_client_method=no.The libcurl.so have compiled, but curl compile failed.

I found the Makefile in the src, "LIBCURL_LIBS = -lssh2 -lssh2 -lssl -lcrypto -lssl -lcrypto -lz -lrt" and "curl_LDADD = $(top_builddir)/lib/libcurl.la -lssl -lcrypto -lz -lrt".The curl_LDADD should be error, but why?The configure file has some bugs?
What should i do to build it ?
Thanks！

So what fails? Show us the error. Also, note that we fixed a libssh2 build issue even in 7.51.0 for when having multiple libssh2 libs installed when configure runs.

[kingbrant]

Thank you very much!
"curl_LDADD = $(top_builddir)/lib/libcurl.la -lssl -lcrypto -lz -lrt" cause it will not link libssh2 when buld curl,so the following errors report：

Clearly the configure script first finds libssh2 successfully since it can detect it fine, and it actually links with it to make sure that it works in the configure script. But then for some reason the linker can't find it or use it when you run the makefile later. But I can't tell exactly why this happens.

[bagder]

Did you perchance build/install only a static libssh2 library? When linking curl, it isn't supposed to specify libssh2 because curl doesn't use libssh2, only libcurl does.
