Subject: [PATCH] Fix compilation without zlib
|
|
|
|
libtelnet source code uses '#if defived(HAVE_ZLIB)' as conditional flag for
|
|
optional compression support. But the configure(.ac) script does not play well
|
|
with this: it will define 'HAVE_ZLIB' to either 1 (zlib present) or 0
|
|
(zlib not present). For the C preprocessor, both cases mean 'defined'.
|
|
|
|
As a result, compilation will fail when trying to include zlib.h, which is
|
|
missing.

Upstream-status: upstream has changed to cmake iso autotools (but not yet
|
|
released) [1] and a pull request exists to fix several issues with that,
|
|
including correct handling of zlib detection [2].
