Linker error using libcurl under MAC

[flashbob]

Hi,
I would like to receive emails via SSL/TLS under MacOS (High Sierra v 10.12.6) and had a look at the code from "infratec" at the following link:
https://www.purebasic.fr/english/viewt ... t=libcurl

Using Windows 7 the code works fine, under MacOS I got following linker errors using different PB Versions:

PB 5.73: Id: warning: object file (/Contents/Resources/compilers/debugger.a/Debugger.o) was build for newer version ( 10.8 ) than beeing linked...
PB 6.04: Id: warning: object file (purebasic.o) was build for newer version ...
PB 6.10: Undefined symbols for curl_easy_setopt", received from: _mainin purebasic.o ...

I'm using default system lib for MAC (curl/libcurl 7.4.5.0)

Any ideas ?

For this you need the external libcurl.

Have you set the constant #LibCurl_ExternalDLL = #True

In front of the include of LibCurl.pbi

Why should I use an external lib under MacOS when it is already delivered with every OS ?
I think that the libraries in the respective PB version do not fit the operating system.

We also know that from Scintilla. Using PB 5.73 I can compile a form including Scintilla gadget.
Under PB6.04 orPB 6.10 there are linker errors ...

I fixed it.

Please download the file again.

Thank you very much for your quick answer and the code changes in libcurl.pbi. The library now runs without errors.
Here some test results I did with Windows 7 SP2 x64 and MacOS Sierra 10.12.6:

Code: Select all

- libcurl.pbi demo : Windows -> ok
                     Mac     -> ok

- GetCertInfo.pb   : Windows -> Certification Info ok
                     Mac     -> 0 certs!                                !!

- pop3.pbi         : Windows -> Message List ok
                             -> no Message Header (Date, From, Subject)   !!
                             -> curl_easy_perform() failed: Couldn't resolve host name
                                using IP instead works, but without message header ..
                     Mac     -> Message List ok
                             -> Message Header ok

- Asynchronous.pb  : Windows -> ok  
                     MacOS   -> linker error

- HTTPRequestI.pbi : Windows -> ok
                     MAC     -> ok
                     
EmailWithFileAttachment.pb : Windows -> Failure when receiving data from the peer
(Port 465)                   MacOS   -> linker error

Perhaps this helps ?
Regards

pop3.pbi works for me in windows with a gmx.net account.

Also EmailWithFileAttachment.pb works for me in windows with a web.de account.

I will test macOS tomorrow.

macOS (Sonoma 14.5)

GetCertInfo.pb : Ok
3 certs!
...

EmailWithFileAttachment.pb: Ok

The curl_mime stuff was added in libcurl 7.56.0

What is reportet from libcurl.pbi ? (Sierra 10.12.6 is not really up to date)

Hi again, this is my report:

--- LibCurl Info ---
Version: 7.54.0
Host: x86_64-apple-darwin16.0
SSL: SecureTransport
Libz: 1.2.8

Protocols:
dict
file
ftp
ftps
gopher
http
https
imap
imaps
ldap
ldaps
pop3
pop3s
rtsp
smb
smbs
smtp
smtps
telnet
tftp
--- LibCurl Info ---

You are right, not really the latest OS. But based on the application it is still enough
I installed XCode 8.3.3 on this machine...

When I start curl in the console, I get the following information regarding the relevant protocols:
curl 7.54.0 libcurl
SSLv2, SSLv3, TLS 1.0, TLS 1.1, TLS 1.2, TLS 1.3

I have another (clean) Mac 11.6.8 but without Xcode installed (don't want to). So I can try with compiled versions...

---

Yesterday I got the message: "invalid memory access" using pop3.pb. Then I customized the library by deleting all parts related to Windows and Linux. After that the error message stopped appearing. But GetCertInfo.pb runs with "no certs", I continue testing ...

Once again thanks for your support !!

By the way: I use an account of my own domain. MultiPart is working fine using command "pop3_GetMessageByNumber(...)"
But only with modified lib...
