Too many functions exported in TDengine database libtaos.so/libtaos.dylib - database

on macOS:
nm -g debug/build/lib/libtaos.1.dylib
shows, that not only functions declared in taos.h are exported in dynamic library, but also internal functions, which is not elegant.
I would say this operation might cause some potential security vulnerability in target machine.

How to extract function names from a library / binary

I have a library with debug symbols, and I do the following to extract function names:
$ objdump -S -D library_name.so > library_name.asm
$ grep -rn ">:" library_name.asm
This gives me what I want:
3101:0000000000002190 <memset#plt>:
3106:00000000000021a0 <close#plt>:
but seems a bit awkward ... Is there a better way to achieve this?

I think the utility you're looking for is nm:
It collects all the symbols, both static and dynamic, defined in a library or any ELF file.
The output looks like this:
000000ec T main
000003f0 a REG_HID0
000003f1 a REG_HID1
00000ec4 T RSA_bigint_add
000009e0 T RSA_bigint_clear
00000a0c T RSA_bigint_cmp
00000dd8 T RSA_bigint_gen

GCC Linker cannot locate library

I'm trying to compile the PCRE library into a testing executable.
The documentation states that running Make and then configure should generate the library.
In the PCRE source directory:
Make
./configure
gcc -o test test.c -L . -lpcre
However the following error returns:
/usr/bin/ld: cannot find -pcre
collect2: error: ld returned 1 exit status
Note: I've also tried flag -libpcre. I was able to sucessfully run this on MacOS (seperately compiled but same library source code and same testiing source code).

Try -lpcre not -libpcre when you link. -l assumes the lib prefix and takes the name of the lib so -lpcre looks for libpcre

glXCreateContextAttribsARB not found (on OpenGL 4.2 driver, GLX 1.4)

Strangely enough, despite the fact that I have GLX 1.4, it appears that I don't have glXCreateContextAttribsARB in my repos.
I wonder if there's any reasonable explanation for this? This can't be a common issue.

Obviously buffer binding, ARB, and all that other nice stuff is supported, but why not glXCreateContextAttribsARB?
Even stranger, what I do have is glXCreateContextAttribsARBPRoc, which I'm curious to know if it would serve as an alternative?
This compiles, for example:
`glXCreateContextAttribsARBProc glxccarb = 0;`

When you say "don't have", I assume you mean "if I try to call a function of this name directly, my app won't link".
That's somewhat by design. The list of functions directly exported from libGL is not growing. If it did, an app that links against a (function exported only by a) new libGL would fail to even launch against an old one. That's bad.
glXCreateContextAttribsARB, like all other extension functions, should be looked up using glXGetProcAddressARB. Better yet, use GLEW so you don't have to worry about this level of detail again.

Visual Studio 2005 always relinks the project when the project is generated with CMake

I have a project in Visual 2005 generated using CMake, and everytime I press F5 the linker relinks the objects, even if no modification was done. I have read other questions with similar problems, but the solution for them was:
The time of the windows was wrong. It was making the executable to be created with the time in the future. Or
The PDB created by the linker and by the compiler had the same name.
I've checked that and I don't have that problem. Also, I have another solution for the project (that was not generated by CMake) and it works fine. I've checked the properties of each project and they are similar.

remote4 - 0 error(s), 0 warning(s)

I've (finally!) found out what my problem was.
I have a project with some sub-directories. In the CMakeLists.txt of each subdirectory, I was defining a project name (with the command project() ). This was causing visual studio to behave like that.
When I removed the project() of the sub_directories the problem was solved.
