QUESTION
I compiled 2 shared libs with --static-libstdc++ enabled.
The 2 shared libs have the same function f
, which just outputs a string and an integer to stdout.
Main program will load the 2 shared libs using dlopen
, and call the f
in it using dlsym
.
However, the second loaded shared lib failed to output the integer and the C++ stream cout
becomes bad & fail
.
ADD: After discussion, I know this is normal... However, I want to change my question to: what implementation of libstdc++ caused this issue? Is there any shared global state? I think if there is no shared global state, it shouldn't be a problem. I wrote the similar program in Windows by static linking to VCRuntime and using LoadLibrary, and it works normally. So why libstdc++ is designed like this?
The following is the code for 2 shared libraries. (They share the same code)
They will just cout
a string and a integer.
ANSWER
Answered 2020-Aug-31 at 15:54Finally I found a way to resolve the issue in Linux (GNU Extensions).
Use dlmopen
which provides better isolation btw objects.

I'm trying to build my first mobile application with flutter and firebase. When I try to display and store a photo I have the following issue :

QUESTION
I'm trying to create a data tree from strings that are expanded by at least 1 letter that is reachable from the current start word. My starting word in this case Dog and the ending word i want for this case would be maybe cat. I have to check that the word from the dictionary is the same size and not already in the vector words and also that if it only 1 letter difference. Below I have tried already implementing this type of thinking but I think I'm missing something crucial. That I need help looking for or maybe add to my code.
...ANSWER
Answered 2019-Oct-09 at 23:48To avoid an infinite loop, you need to remember words that you have already seen. In the following code example, I use an unordered_set
for that (add #include
.
Then, the code could look like this:

QUESTION
This code is a programming assignment for Andrew Ng's machine learning course.
The function is expecting a row vector [J grad]
. The code computes J
(albeit wrongly, but that's not the issue here), and I put in a dummy value for grad
(because I haven't written the code to compute it yet). When I run the code, it only outputs ans
as a scalar with the value of J
. Where did grad
go?
ANSWER
Answered 2017-Apr-24 at 11:12You have specified in your function declaration that the function can simultaneously return more than one output value:
