Custom Query (545 matches)

I tried to compile Lemon on Mac, but I got both warnings and errors, see the attached compilation log.

The compiler in use was:

$ gcc --version
i686-apple-darwin9-gcc-4.0.1 (GCC) 4.0.1 (Apple Inc. build 5465)
Copyright (C) 2005 Free Software Foundation, Inc.

I used the following configuration parameters:

./configure --enable-demo

This bug is reproducible in [f4e4dbc1d467].

Here comes two proposed interface for the reader (we might want to implement booth):

• sectionStream(std::string name,F f). Here the parameter name is the section name (the word after @), while f is an unary functor, with an std::istream& parameter. When the reader finds a section that matches with name, then it calls f with an istream pointing to right after the section header line. f is required to recognize the end of the section and not to read further. Finally, f should return the number of read lines.
• sectionLines(std::string name,F f). Here f takes an std::string as argument, an it will simply be called with each line of the matching section.

It would be important to have a section reader in LEMON 1.0, as it is necessary to port glemon.

The following type of constraints are valid in the Lp system:

LpExpr(e) >= double(l) <= double(u),[[BR]]

and the meaning of it is

double(l) <= LpExpr(e) <= double(u).[[BR]]

The solution is easy, if an expr is on the left side of comparison, then the other bound must be also set to +/- Inf, it must not let NaN.
