Re: [HTCondor-users] Condor compilation problems in upcoming Fedora 36

I'll work on this for the 9.0.13 release. Sorry, 9.0.12 was already frozen.

Subject: [HTCondor-users] Condor compilation problems in upcoming Fedora 36

Dear Condorists,

Did anyone manage to compile a recent Condor on Fedora-36 (out later
this month)?

I get a nasty looking error in condor_auth_passwd.cpp:

In static member function 'static int Condor_Auth_Passwd::hkdf(const
unsigned char*, size_t, const unsigned char*, size_t, const unsigned
char*, size_t, unsigned char*, size_t)':

evp_md_st*'} [-fpermissive]

A similar error is reported a few more times in the same file.

This is with gcc 12.0.1, and openssl-devel 3.0.2.

On Fedora 35, the same builds clean (which gcc 11.2.1 and

I'd suspect the openssl version jump is to blame, as there are also a
lot of warnings about
RSA_<anything>() being deprecated.
