Replying to ladanyi:

This is a very mysterious error.

lp.colUpperBound(x,1);

fails to compile when x is and std::vector<LP::Col>, but there is no problem with

lp.colLowerBound(x,1);

The implementation of these functions are exactly the same.

Also, everything is fine with VS2008. (Well, in this respect... :) )

[Tapolcai János]

Moreover if you swap the code lines in lp_base.h related to colUpperBound and colLowerBound

lp.colUpperBound(x,1);

is going to compile and

lp.colLowerBound(x,1);

is not.

The attached patch ticket209_67d4e07336d7.patch fixes the bug. The bug and the solution is not too meaningful bug.

Could someone have a look at this ticket so that we can put it in the main branch?

The changeset (with different commit log) is in the main branch now, see [2eb5c8ca2c91].
