Hello everyone,

I'm trying to compile curl on my Solaris 11.3 server.
My server has a default OpenSSL installation (1.0.1q) and a compiled 1.0.2g under /somedir/openssl/1.0.2g.
I executed configure with:
PKG_CONFIG_PATH=/somedir/openssl/1.0.2g/lib/pkgconfig:$PKG_CONFIG_PATH ./configure --prefix=/somedir/curl/7.48.0
and get a warning:

checking for OpenSSL library version... 1.0.1
checking for OpenSSL library version... 1.0.2
checking for OpenSSL headers and library versions matching... no
configure: WARNING: OpenSSL headers and library versions do not match.

When i execute configure with
CPPFLAGS=-I/somedir/openssl/1.0.2g/include:$CPPFLAGS PKG_CONFIG_PATH=/somedir/openssl/1.0.2g/lib/pkgconfig:$PKG_CONFIG_PATH ./configure --prefix=/somedir/curl/7.48.0
The same thing happens.

How can I tell the configure script where to search for the correct 1.0.2g headers?

Looking into the configure script:
My set CPPFLAGS is overridden by other flags which are empty at runtime.

> OLDCPPFLAGS=$CPPFLAGS
> # CPPPFLAGS comes from CURL_CPP_P
> CPPFLAGS="$CPPPFLAGS"

Then a header is generated

> cat confdefs.h - <<_ACEOF >conftest.$ac_ext

which includes openssl/crypto.h

# ifdef USE_OPENSSL
# include <openssl/crypto.h>
# else
# include <crypto.h>
# endif

#ifdef OPENSSL_VERSION_NUMBER
CURL_DEF_TOKEN OPENSSL_VERSION_NUMBER
#endif

and "gcc -E" is executed on some conftest.c which probably replaces the macros:

> tmp_exp=`eval "$ac_cpp conftest.$ac_ext" 2>/dev/null | \

After that the OPENSSL_VERSION_NUMBER is set to the old 1.0.1 OpenSSL, probably because the "ac_cpp" variable uses the now empty "CPPFLAGS" and so doesn't include my own include dir.

Is that how the header<->library version compare is intended?
