I realize I need to define QCOM has the vendor somewhere, but which file / where is this typically declared?
I am getting the following exception while building the ROM for a lineageos project and need some help diagnosing and resolving the issue:

I don't know the long term fix for this issue, but my quick and dirty fix was to define the variable in both of the files that depend on it.
I went into the file hw_info_drm.cpp and added the following at the top:
#define QCOM 1
When running clang-tidy on this minimal example posted below I get the (imho) false positive error from clang-tidy (full error trace at the end)
Value assigned to field 'id' in implicit constructor is garbage or undefined [clang-analyzer-core.uninitialized.Assign]
The code does nothing but assign a boost::variant to one of the two values. The error is gone if I replace the copy constructor by Size(const Size& sz) = default;. However, I cannot do this, since the Size is a cv::Size in the real code.
Even though it might not be as elegant as possible, I don't see any error with this. Can somebody point me into the direction if I am mistaken, clang-tidy or boost.
#include <boost/variant.hpp>
class Size
{
public:
Size() = default;
Size(const Size &sz) : width(sz.width) {}
int width{0};
};
struct B {
Size size;
};
struct A {
Size size;
uint32_t id{0};
};
int main() {
using T = boost::variant<A, B>;
T config = B();
}

What should I do to avoid this?
You're working with an elderly codebase, so some surgery is required. Alas.
The four offending declarations in bltNsUtil.h need to be removed as Tcl now declares them properly; Tcl_FindCommand, Tcl_CreateNamespace, Tcl_FindNamespace and Tcl_Export are part of Tcl's public API and have been for years. (The problem declarations are on lines 50, 67, 72, and 75, plus probably one or two lines further in each case.)
Also, you're recommended to not use sudo while doing the build itself, but rather just when doing the install afterwards. Mere compilation of the code shouldn't require elevated permissions.

Any help would be appreciated. Thank you.
Here's what I did on a linux CUDA 7.5 setup:
Update the GPU driver to 352.79. In my case, this was done via the runfile installer here. If you have previously installed the GPU driver via the package manager method (e.g. .deb) then you don't want to use the runfile installer method.
get the latest version of the GDK (see note below), which at this time happens to target 352.79, and includes nvml:
wget --no-check-certificate http://developer.download.nvidia.com/compute/cuda/7.5/Prod/gdk/gdk_linux_amd64_352_79_release.run
install the GDK:
sh gdk_linux_amd64_352_79_release.run
verify that the appropriate libraries were updated:
ls /usr/lib64/libnv*
(and you should see libnvidia-ml.so.352.79 etc.)
compile the example file:
g++ -I./gdk352_79/usr/include -L/usr/lib64 -lnvidia-ml example.c -o example
When I run the example executable, I get:
$ ./example
Found 2 devices
Listing devices:
0. Quadro 5000 [0000:02:00.0]

All done.
Press ENTER to continue...

Hopefully this will get you going. I am assuming you don't need help making any Makefile changes if needed. If your Makefile is not working, keep modifying it until you get the exact compile command I list in step 5.
NOTE: As of CUDA 8.0, the GDK is not a separate entity but is installed with CUDA 8.0 toolkit. It should not be necessary to install the GDK separately.
I am using htmlcxx library for a simple program but I got stuck in a problem, I searched many other related solutions but my problem is still a problem, Hope any one can help me, Here is the code I used in Kdevelop on Ubuntu:
#include <iostream>
#include <string>
#include <htmlcxx/html/ParserDom.h>
using namespace htmlcxx;
int main()
{
//Parse some html code
std::string html = "<html><body>hey</body></html>";
HTML::ParserDom parser;
tree<HTML::Node> dom= parser.parseTree(html) ;
//Print whole DOM tree
std::cout << dom << std::endl;
//Dump all links in the tree
tree<HTML::Node>::iterator it = dom.begin();
tree<HTML::Node>::iterator end = dom.end();
for (; it != end; ++it)
{
if (it->tagName() == "A")
{
it->parseAttributes();
std::cout << it->attribute("href").second;
}
}
//Dump all text of the document
it = dom.begin();
end = dom.end();
for (; it != end; ++it)
{
if ((!it->isTag()) && (!it->isComment()))
{
std::cout << it->text();
}
}
return 0;
}
