After a fresh 'emerge --sync' set about to an 'emerge -u world' and stumbled across a ppp build failure.

(In reply to comment #0) The same thing, temporary workaround by disabling eap-tls
Works for me. The MD5_CTX type is defined in md5.h . Maybe on your system __MD5_INCLUDE__ is defined through other included header file?
(In reply to comment #2) > Works for me. The MD5_CTX type is defined in md5.h . > Maybe on your system __MD5_INCLUDE__ is defined through other included header > file? > Well, there are many instances of md5.h on my system. Several in each /usr/src/<linux-kernel-version>/ Several in /usr/include for varying programs, athena widgets, php, would it help to get a list of these? If it is dependent on the kernel, I suppose it'd be because I have the eap-tls use flag enabled, and it might require that to be supported in my gentoo-sources massaged config, except that I don't see that declared anywhere in any of these headers. Running: for file in `locate /md5.h`; do grep '__MD5_INCLUDE__' $file; done came up with nothing after an updatedb.
Please look for the cause of your problem. I can't fix it if I don't know what caused it, can I? Hints: 1) make sure the local md5.h file is the one used by the compiler. Place an #error "Local file used" at the beggining of the /var/tmp/portage/ppp-2.4.4/work/ppp-2.4.4/pppd/md5.h file and run make 2) search for __MD5_INCLUDE__ in *all* include files grep -r __MD5_INCLUDE__ /usr/include

Don't imagine you could, unless part of the gentoo dev/bugfix qualification is a psychic power test. Going with what you suggest for the hints. > > Hints: > 1) make sure the local md5.h file is the one used by the compiler.

Except for the recursion warning by grep. Oddly enough I'm finding that one program now reports missing headers, alut.h from the openal project is called out by the flightgear flight sim, new and old profile. Not appropriate to go into here in depth, unless you think this is a sign of a broad misconfiguration on my part. Currently I'm just masking out any greater version of ppp than the current one, so as not to break my ability to tunnel if I need to. Appreciate the suggestions with this, hope the information helps narrow something down.
in eap.c, the line #include "md5.h" is commented!? why!? after uncommenting it, it compiles fine! (BTW: md5.h is included in pppd's sources)

i guess it has been introduced with openssl 0.9.8 since the error first occured for me when recompiling ppp after upgrade to openssl 0.9.8b/c
the first comment was about chap-md5.c, not eap.c! Please test the following: 1) ebuild ppp-2.4.4-r1.ebuild unpack 2) uncomment #include "md5.h" from eap.c 3) ebuild ppp-2.4.4-r1.ebuild compile For me, it builds just fine if I don't uncomment the include and fails if I uncomment it: i686-pc-linux-gnu-gcc -march=athlon-xp -O3 -pipe -DHAVE_PATHS_H -DIPX_CHANGE -DHAVE_MMAP -I../include '-DDESTDIR="/usr"' -DCHAPMS=1 -DMPPE=1 -DHAS_SHADOW -DHAVE_CRYPT_H=1 -DUSE_CRYPT=1 -DUSE_PAM -DHAVE_MULTILINK -DUSE_TDB=1 -DPLUGIN -DPPP_FILTER -DINET6=1 -DCBCP_SUPPORT -DMAXOCTETS -c -o eap.o eap.c In file included from /usr/include/openssl/evp.h:84, from /usr/include/openssl/x509.h:67, from /usr/include/openssl/ssl.h:177, from eap-tls.h:37, from eap.c:72: /usr/include/openssl/md5.h:105: error: conflicting types for

I've discovered what was the problem. The new openssl (0.9.8.c) no longer includes <openssl/md5.h> in openssl/ssl.h. Fixed (without revision bump) in ppp-2.4.3-r16 and ppp-2.4.4-r1, by including <openssl/md5.h> in eap.c. I've tested both ebuilds against dev-libs/openssl-0.9.7j and dev-libs/openssl-0.9.8c.
