Dave Borowitz dborow...@google.com writes: Use this only when CURLDIR is not explicitly specified, to continue supporting older builds. Moreover, if CURL_CONFIG is unset or running it returns no results (e.g. because it is missing), default to the old behavior of blindly setting -lcurl. ifdef CURLDIR + CURL_LIBCURL= else + CURL_CONFIG ?= curl-config + ifeq $(CURL_CONFIG) + CURL_LIBCURL = + else + CURL_LIBCURL := $(shell $(CURL_CONFIG) --libs) endif This ifeq is redundant and will never set CURL_LIBCURL to empty without running the else part, I think. In a Makefile, a variable explicitly set to empty and a variable that is unset are treated the same. $ cat Makefile EOF CURL_CONFIG ?= curl-config ifeq $(CURL_CONFIG) X=Empty else X=NotEmpty endif ifdef $(CURL_CONFIG) Z=Defined else Z=Undefined endif all:: @echo $(X) $(Z) EOF $ make -f Makefile CURL_CONFIG= Empty Undefined That does not mean the patch will give us a broken behaviour, though.

I haven't checked what it would look like if we turn this into an incremental patch to be applied on top of 'master' (which would give us a place to document better why we do not rely on the presense of curl-config), but if we can do so, that would be more preferable than having to revert the merge of the previous one and then applying these two patches anew.

And I just checked; it is not very pretty to call it trivially correct, and I would feel safer to revert the merge for 2.0, and queue the new one for the next cycle, cooking it in 'pu' and then 'next' in the meantime. -- To unsubscribe from this list: send the line unsubscribe git in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
