dlopen

问题 Since a couple of days, I constantly receive the same error while using MATLAB which happens at some point with dlopen . I am pretty new to MATLAB, and that is why I don't know what to do. Google doesn't seem to be helping me either. When I try to make an eigenvector, I get this: Error using eig LAPACK loading error: dlopen: cannot load any more object with static TLS I also get this while making a multiplication: Error using * BLAS loading error: dlopen: cannot load any more object with

问题 I have a shared library which I want to access symbols from the main program. For example: main.c #include <stdio.h> void bar(void) { puts("bar"); } extern void foo(void); int main(void) { foo(); return 0; } foo.c #include <stdio.h> extern void bar(void); void foo(void) { puts("foo"); bar(); } I compile and run like: gcc -c -fpic foo.c gcc -shared -o libfoo.so foo.o gcc -L$(pwd) -o test main.c -lfoo ./test And I get the output I expect: foo bar However, I must use dlopen() and dlsym() because

问题 Anybody knows if actually exists a wrapper or ported library to access to Unix dynamic linker on Python? 回答1: Would ctypes do what you want? 回答2: The module is called dl: >>> import dl >>> dl.open("libfoo.so") <dl.dl object at 0xb7f580c0> >>> dl.open("libfoo.so").sym('bar') 1400432 ... though it's nasty and you might want to consider using ctypes or an extension module. Edit Apparently, dl is deprecated in 2.6 so you'll want to use ctypes which has a better API anyhow. 来源： https:/

问题 Im writing a simple plugin-based system in Rust to gain some skills and experience using the language. My system dynamically loads libraries and executes them at runtime to initialize each plugin. Im running into an interesting segfault issue when executing code from a dynamically-loaded library. This is the code to load and run the plugin init function: (this bit works fine) pub fn register_plugins<'rp>(&'rp mut self) { let p1 = match DynamicLibrary::open(Some("librust_plugin_1.so")) { Ok

问题 I have a C++ library (.so) which is opened using dlopen() by another application. But I need to find the code coverage of this library while run within the application using gcov. Is it possible? If yes, how can it be done? If not, how can the issue be resolved? 回答1: Firstly have your compiled your C++ library with the --coverage flag? I've never actually used a '.so' library with gcov before, so I'm not sure it would work anyway. Secondly could you arrange a test version of your application

问题 I'm trying to use sprof to profile some software (ossim) where almost all the code is in a shared library. I've generated a profiling file, but when I run sprof, I get the following error: > sprof /home/eca7215/usr/lib/libossim.so.1 libossim.so.1.profile -p > log Inconsistency detected by ld.so: dl-open.c: 612: _dl_open: Assertion `_dl_debug_initialize (0, args.nsid)->r_state == RT_CONSISTENT' failed! The instructions I was following said that I needed libc version at least 2.5-34, I have

问题 Everything is in the title really. The man page does not say anything. Some google reports some people checking errno after dlopen, but just few and with various results. The function does return a success/non-success value, but how should one figure out the cause of the failure. So does dlopen() set errno? where are the different errno values defined, then? If not, what should be used to check what caused the failure? 回答1: No (emphasis added). Upon successful completion, dlopen() shall

问题 When I am loading my application through android studio, I am getting following error: I have compiled SDL2 library separately using Android.mk/Application.mk and added those so paths in my application. buildToolsVersion = '23.0.2' minSdkVersion.apiLevel = 17 targetSdkVersion.apiLevel = 23 Error FATAL EXCEPTION: main Process: com.example.hellojni, PID: 14607 java.lang.UnsatisfiedLinkError: dlopen failed: library "libSDL2.so" not found at java.lang.Runtime.loadLibrary(Runtime.java:372) at java

问题 I have developed an application which uses 32 bit library libmylibrary.so but when I use system.loadLibrary("mylibrary") , it says that cannot find library in /system/lib64 or /vendor/lib64 . I don't see my library in /data/app-lib .. etc . My Android version is 5.1.1 . I even copied my library in /system/lib64 but it is still giving error message that dlopen failed to load 32 bit instaed of 64 bit . Please provide some valuable suggestions. 回答1: it says that cannot find library in /system

问题 I am about to fix this issue. I read several queries regarding dlopen but still not clear. It seems dlopen is allocating memory by either calloc or malloc. But how to deallocate this memory? Similar code pointing leak problem here for "dl" (snip) Event alloc_fn: Called allocation function "dlopen" Event var_assign: Assigned variable "dl" to storage returned from "dlopen(&"libc.so.6",1)" 261 dl = dlopen("libc.so.6", RTLD_LAZY); At conditional (1): "dl" taking true path 262 if (dl) { Event
