It is due to in tomcat 7 by default SKIP IDENTIFIER CHECK feature is false.

Hence supply-Dorg.apache.el.parser.SKIP_IDENTIFIER_CHECK=true as an argument while maven clean installing.

JSP pre-compilers avoid a JSP compilation delay when a JSP page is first hit.

It is an optimization that may or may not be actually worth it, but for high-page-count high-usage sites that use server-side HTML generation it may be worth it.

For example, see https://www.mulesoft.com/tcat/tomcat-jsp

Questions like this can be self-answered by searching the web. The first step is to identify what you're looking at, which it appears you did, since you identified the dependency as a JSP compiler.

Once you know what you're trying to look for, ask the web "why use a JSP compiler" or something similar. The reference I posted above was one of the early results when I searched for this.

Where are the NVCC codes for a specific warning listed?

They are not publicly available. There is no list. There is no straightforward way of doing what you want without some combination of:

1. Promoting all warnings to errors and forcing the device front end/compiler to emit error codes not textual messages, and then
2. Snooping around in the EDG front end documentation and the files and documented distributed by other compilers which also use the EDG front end to see if you can find a matching code, otherwise
3. Dumping strings and snooping around in the cudafe executable to see if you can find the string you are looking for, and then see if you can reverse engineer back to a warning code or enumeration

In short, you really have to want this badly and have time to invest, and even then it might not be possible.

Alternatively, register in the NVIDIA developer program, raise a bug and see if they will help you with the information you need.

So, apparently it's disabled by default on your platform; this behavior is configurable when gcc is built from source, and this is what your OS or packager chose to do. Use -fstack-protector to enable it (if your platform supports it at all).

For more about how gcc's stack canary system works, see Stack smashing detected.

In ordinary English, a canary is a type of bird that was used to detect toxic gases in mines. The birds were more sensitive to these gases than humans are, and so if the bird died, this could alert the miners to the danger while they still had time to evacuate. The analogy is that the value on the stack is like a canary: if it "dies" (is overwritten) then the program can "evacuate" (abort) before an exploit can occur.

Yes, it's related to the version of flex you are running.

Unlike lex and very old versions of flex, any flex you're likely to come across doesn't define (or initialise) yylineno unless you run it in lex-compatibility mode (not really recommended) or request that flex tracks line numbers (highly recommended but not done by the source code you're using).

So you have the following options, roughly in order by my prejudices: Only do one of these! They are not compatible with each other.

1. Add %option yylineno to the beginning of the c.l file. Then change line 5 to:

MSVC is not able to detect this even with /W4 /c or /Wall and additional linter is required, e.g. clang-tidy is detecting this (courtesy to Stephen Newell).

When using g++ compiler, you are looking for -Wsign-conversion compiler option.

You can edit your .R/Makevars file and append the desired flags using the += operator, e.g.

The beresp object is not available in vcl_deliver as it is part of a different flow. The equivalent would be resp, which would result in the following header.copy() line:

Varnish Cache, the open source version of Varnish doesn't support dynamic backends.

When the VCL file is loaded and compiled, the .host and .port values need to be strings, not expressions.

The error message also indicates this:
