Build tarsnap on cygwin
Hi all,
I attempted to build tarsnap on cygwin, but it complained about not
finding OpenSSL. After trying various cygwin packages that looked like
they provided it, I did a google search and found a person whose
solution was to download/build/install OpenSSL from source code.
When I did that I ran into an OpenSSL bug[1] but they fixed it and now
it builds and installs (or so it says).
Unfortunately, tarsnap still says it can't find OpenSSL. Is there an
option I can give to tarsnap to tell it that it should be looking for
OpenSSL in /usr/local/ instead of the standard place? Or is there any
other advice for building tarsnap on cygwin when it says it can't find
OpenSSL?
When I look at the config.log, it complains about gcc .... -lcrypto
where it can't find crypto. When I look for it, I see it in the location
/usr/local/lib/libcrypto.a and libcrypto.dll.a.
$ find /usr/local/ | grep crypto
/usr/local/bin/cygcrypto-3.dll
/usr/local/include/openssl/crypto.h
/usr/local/include/openssl/cryptoerr.h
*** this one *** /usr/local/lib/libcrypto.a
*** this one *** /usr/local/lib/libcrypto.dll.a
/usr/local/lib/pkgconfig/libcrypto.pc
/usr/local/share/doc/openssl/html/man3/ERR_load_crypto_strings.html
/usr/local/share/doc/openssl/html/man3/OPENSSL_init_crypto.html
/usr/local/share/doc/openssl/html/man7/crypto.html
/usr/local/share/man/man3/ERR_load_crypto_strings.3
/usr/local/share/man/man3/OPENSSL_init_crypto.3
/usr/local/share/man/man7/crypto.7
Any ideas or suggestions greatly appreciated.
V/r,
Bryan
