Re: [gccsdk] Building libssh2 fails while building nettle with the autobuilder. Any clues?

Lee,
I have successfully built Nettle. I had to make a number of tweaks to
various components to get that to all work.

For libgpg-error0:
Add : cp src/syscfg/lock-obj-pub.arm-unknown-linux-gnueabihf.h
src/syscfg/lock-obj-pub.riscos.h
To: autobuilder/libraries/libgpg-error0/setvars

For ssh2:
Add: export LIBS='-ldl'
To: libraries/libssh2/setvars

Google says libgcryp11 has gone from Jessie so I built libgcryp20 instead.
cp -a ../autobuilder/libraries/libgcrypt11/
../autobuilder/libraries/libgcrypt20


# Edited
Sunfish#192.168.9.119::/home/alan.$.autobuilder.network.nettle.depends
made it libcrypt20 as shown below.
libssh2
libgcrypt20
libgpg-error0
zlib1g

# Nettle

Sunfish#192.168.9.119::/home/alan.$.build.nettle.nettle.GNUmakefile
Added -ldl to LIBS making it as follows:

LIBS = -lssh2 -lz -lgcrypt -lgpg-error -lcrypto -ldl

I have started to look at the proposition of getting nettle to do
Public/private key auth and it looks ok. My intention is to co-opt the
current 'Command' field/icon to hold two space separated file names for the
key files initially. If that works I may extent the UI to better
accommodate the extra fields.

I do have one more question if I may.

The second thing I am interested in doing is to take Alex Waghs !SunFish nfs
client and replace the nfs specific components with sftp. Essentially
making sshfs for RISC OS. To do this I am going to need the module build of
libssh2. I had a look at what autobuilder has made by default and that is
just the normal application version. My question therefore is how do I get
the auto builder to make me the module linkable version as well?

Many thanks for your help and hints its most appreciated.

Alan

I may have given you the wrong impression; when I said the build runs to the
end without error, I meant libssh2 not nettle. So I'm afraid I hadn't built
libgpg-error0. Trying it now I get the same error.

It looks like the file syscfg/lock-obj-pub.riscos.h is supposed to be
generated once and added to the source tree with the others. You could try
copying one of the others, eg,
syscfg/lock-obj-pub.arm-unknown-linux-gnueabihf.h
which I think has the right size for the _priv struct member.

Lee.
