[strongSwan-dev] [PATCH] Force libtls when libpttls is enabled

[Thomas De Schampheleire]

The libpttls library expects libtls.la to be present:
libpttls_la_LIBADD = $(top_builddir)/src/libtls/libtls.la
but there is no expressed dependency between them. Therefore, it is possible to
create a configuration where libpttls is enabled and libtls is not, causing a
build failure:

make[4]: *** No rule to make target `../../src/libtls/libtls.la', needed by `libpttls.la'.  Stop.

libpttls is enabled through USE_PTTLS, set when tnc_tnccs == true.
  tnc_tnccs is true when any of tnc-imc, tnc_imv, tnccs_11, tnccs_dynamic or eap_tnc is true.

libtls is enabled through USE_TLS, set when tls == true.
  tls is true when any of eap_tls, eap_ttls or eap_peap is true.

This patch forces tls to true, when tnc_tnccs is true, so that the required libtls.la dependency
is built before it is used by libpttls.
