[Mamoru TASAKA]

with --enable-oldapps option, with ngspice-34 tarball, ngsconvert fails to build with
multiple definition:

I just wanted to compile the new ngspice-34 and faced the same issue.
In addition to the multiple definition messages I get a huge number of undefined references (see examples below):

inpcom.c:(.text+0x6c4): undefined reference to INPevaluate' /usr/bin/ld: inpcom.c:(.text+0x744): undefined reference toINPevaluate'

A short test with the ngspice-33 using same ./configuration command was still successful.
Something changed from ngspice-33 to ngspice-34.

[Holger Vogt]

Yes, something has changed, I have no simple solution right now. Since the old apps are deprecated, please compile without --enable-oldapps. If I find a simple solution to this bug, then o.k. If not, I will remove the old apps in the next release.

[Holger Vogt]

I have uploaded a fix to branch pre-master.

Unfortunately the capability to compile ngsconvert is extremely sensitive to changes in
associated files as found in makefile.am and may easily be broken again next time. Requires manual tweaking.

[Wolfgang Walthes]

Works quite well.
Thanks a lot !
