I'm trying to run hand gesture recognition openCV sample project from this link https://github.com/simena86/handDetectionCV. I run the make command in cygwin terminal, but i'm getting error. I run following command in cygwin terminal E:\handDetectionCVmaster\make

That means you miss the pkg-config installation. That is what is also causing the rest of the errors as the output of the pkg-config command could not be invoked, respectively.
Go to the following url, grab it and install it:
http://ftp.gnome.org/pub/gnome/binaries/win32/dependencies/pkg-config_0.26-1_win32.zip
Please note that you might need to install further dependencies from that site, but then it oughta work, basically.

I want to extract text from PDF so I tried QPdfium From here
I tried to compile the library using QT 5.12.0 with Mingw32 compiler I followed this steps:
1 - I git a clone from the project and then open the qtpdfium.pro, select release mode with Mingw 32 compiler.
2 - when i start to build I got around 18 Error

so what is the problem, in the readme file It say that I can compile it with no problem, I tried to compile using MSVC 2017 32 and it give me more errors 187 errors, so please any help if some one compiled it before, or if there any link to download the library in a binary instead of compiling it.
Thanks in advance.

Considering that ARToolkit (without VRML support) is working well and OpenVRML is installed successfully, I can't figure out what is the problem here.
I am trying to compile the PyS60USB for Pys60 2.0 with the Symbian Belle Sdk but for some seemingly unrelated reason I am getting the seemingly random errors about almost everything not naming a type, like these:

ETC...
I am guessing these errors are probably related and are probably caused by some problem with my environment or something. Do any of you have any I idea what could possibly causing all these hundreds of errors?
Looks like you have two incompatible C standard library implementations in your include path. There's the old ESTLIB in epoc32/include/libc and the newer Open C epoc32/include/stdapis. Remove the former from your MMP file include paths. While there, check that you are not linking against estlib.lib.
Disclaimer: It's been a couple of years since I last time touched a Symbian SDK.

Add the following defines:
g++ -DHAVE_NETINET_IN_H -DHAVE_INTTYPES_H ...
Or add #include <stdint.h> before including Thrift.h in your code.
See the discussion at THRIFT-1326. The issue is suppposedly fixed in thrift 0.9.
It looks like your problem is a compiler issue.
It can't find the type "uint32_t"
There is another question on SO regarding this:
'uint32_t' identifier not found error
Quoted from user templatetypedef
This type is defined in the C header which is not currently
a part of the C++ standard. According to the Wikipedia page on the
header, it hasn't shipped with Visual Studio until VS2010.
In the meantime, you could probably fake up your own version of the
header by adding typedefs that map Microsoft's custom integer types to
the types expected by C. For example:
typedef __int32 int32_t; typedef unsigned __int32 uint32_t; /* ...
etc. ... */ Hope this helps!
I am getting the following error for STL files on GCC 4.1.2. And the same code works properly without any compilation errors on GCC 3.4.6.
I am including some built-in headers in my code that in turn include these STL files. Hence, I cannot modify the header files.
I compile it using the following:
gcc -I/grid/0/gs/java/jdk64/current/include -I/grid/0/gs/java/jdk64/current/include/linux -I/grid/0/tmp/direct/include/ydmg/ ydmg.cpp -I/grid/0/tmp/direct/include/ -o libydmg.so
Do I need to include some other parameter while compiling?
Could the compiler version be the cause of this problem?
The error is as follows:
/usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../include/c++/4.1.2/bits/stl_vector.h:157: error: expected type-specifier

Any help would be appreciated.
Here is the C++ code.
I am calling the methods from ydmg and yut libraries using JNI.
This code is working perfectly fine on gcc 3.4.6. Its gives errors on gcc 4.1.2.
#include <stdio.h>
#include "ydmg/bd.h"
#include <jni.h>
#include "yut/string.h"
extern "C" int getAge();
JNIEXPORT jint JNICALL Java_ydmgBd_getAge(JNIEnv *, jobject)
{
ydmgBd bdObject;
yutString s = bdObject.getKeys();
printf("\ngetKeys() returns the key as : %s",s.c_str());
yutHash user;
yutString value = "abc";
yutString key ="login";
user.set(key,value);
ydmgBd bd1(user);
bool val = bd1.save(user);
if(val){
printf("\ntrue");
}else {
printf("\nfalse");
}
int age = bd1.getAge();
printf("\nAge : %d ",age);
printf("\nhi");
return 1;
}
int main(){
return 0;
}
If you compile cpp code with gcc and not with g++, you must link with -lstdc++, so that option is definitely missing.
However, the problem already occurs at the parsing step, so my suggestion is to check the namespaces... e.g. have a look at the error output:
...
ytl::std::operator!=
...
std should not be in your personal ytl namespace. You are doing something wrong with your includes.
One of your header files is almost certainly including:
#include <vector>
Before that line, add:
#undef max
And I believe your compiles will start working. This is happening b/c you are also using the C std library, which for some functions uses macros, and in this case, causes the preprocessor to freak out. I've seen this same error on Linux, and undefining that symbol was all i needed to get things compiling again.
